ghostscript-fonts-grops-1.22.2-bp151.4.2

No version change. Fix building issues:
  * Provide COPYING file.
  In version 9.26, the ghostscript package doesn't provide a
  COPYING file anymore. So providing it.
  * Add missing %config macro for /etc/profile.d/* files

- expand groff_version macro

- fix factory build

- Use %requires_eq

- dynamically create requires to groff with the version instead of
  hardcoding in spec file

- add automatic installation for Polish locale (bnc#856842)

- add sh/csh profiles for setting $GROFF_FONT_PATH (bnc#856842)

- don't install to /usr/share/groff/current but to the symlinked
  target directory

- add missing group tag
- spec file cleanup via osc format_spec_file

- Created from scratch (inspired by personal communication with Werner Lemberg)
