- Packaging improvements:
  * Update to BuildRequires: golang(API) >= 1.21 matching go.mod
- CVEs:
  * CVE-2024-22189 (bsc#1222468)
  * CVE-2023-45142

- Fix --no-check build

- Packaging improvements:
  * Remove define github project name components no longer needed
  * Remove define gname and uname for user and group creation, use
    package name macro with identical value
  * Drop BuildRequires: golang-packaging. The original macros for
    file movements into GOPATH are obsolete with Go modules. Macro
    go_nostrip is no longer needed with current binutils and Go.
  * Use autosetup -a 1 to unpack source and vendored dependencies
  * Drop export CGO_ENABLED="0". Use the default unless there is a
    defined requirement or benefit.
  * Build PIE with pattern that may become recommended procedure:
    %%ifnarch ppc64 GOFLAGS="-buildmode=pie" %%endif go build
    A go toolchain buildmode default config would be preferable
    but none exist at this time.
  * Drop mod=vendor, go1.14+ will detect vendor dir and auto-enable
  * Remove ldflags -s (Omit symbol table and debug info) and -w
    (Omit DWARF symbol table). This information is used to produce
    separate debuginfo packages and binaries are stripped for
    reduced size by GNU strip during RPM build.
  * Add basic %check to execute binary --help

- Drop deprecated go_provides macro: even though it tries to guard
  on suse_version <= 1110, it has entirely disarms the dep scanner.
- Remove the manual user/group provides: the package uses
  sysusers.d; the auto-provides were not working due to the broken
  go_provides.

- Provide user and group (due to RPM 4.19)
- Update caddy.sysusers to also create a group

- BuildRequires: golang(API) >= 1.20 for guic-go bump

- Fix failing build on SLE-12 by defining _sharedstatedir /var/lib
  on SLE-12 consistent with SLE-15, openSUSE and upstream RPM docs.
  * SLE-12 _sharedstatedir was /usr/com, _localstatedir is /var as expected
  * SLE-15+ _sharedstatedir is /var/lib, _localstatedir is /var
  * _sharedstatedir used here as home directory for newly created user caddy
  * If not redefined build fails with empty /usr/com not owned by any package
  * Switch to useradd -d %{_sharedstatedir} from %{_localstatedir}/lib
    The latter is common in Factory packages possibly for historical reasons,
    opt for the less common option here for equivalence and clarity.
