fuse-2.9.9-160000.2.2

- Replace transitional %usrmerged macro with regular version check (boo#1206798)

- Add closefrom.patch [boo#1189086]

- Enable LTO (boo#1133101) and use -ffat-lto-objects.

- Modernize some older specfile constructs. Rediff patch4 as -p1.
- Update descriptions.

- prepare usrmerge (boo#1029961)

- update to 2.9.9:
  * Added OpenAFS to whitelist (so users can now mount FUSE filesystems on mountpoints within OpenAFS filesystems).
  * Added a test of seekdir to test_syscalls.
  * Fixed readdir bug when non-zero offsets are given to filler and the
  filesystem client, after reading a whole directory, re-reads it from a
  non-zero offset e. g. by calling seekdir followed by readdir.

- Move definition of _lto_cflags into %build.

- Disable LTO (boo#1133101).

- Use %make_build in order to provide verbose output.

- fuse 2.9.8
  * SECURITY UPDATE: In previous versions of libfuse it was possible
    to for unprivileged users to specify the allow_other option even
    when this was forbidden in /etc/fuse.conf. The vulnerability is
    present only on systems where SELinux is active (including in
    permissive mode).
  * libfuse no longer segfaults when fuse_interrupted() is called
    outside the event loop.
  * The fusermount binary has been hardened in several ways to
    reduce potential attack surface. Most importantly, mountpoints
    and mount options must now match a hard-coded whitelist. It is
    expected that this whitelist covers all regular use-cases.
- cleanup with spec-cleaner
