media-gfx/nomacs: 3.14.2 version bump. Add plugins support.

The updated nomacs ebuild contains:
- add 'plugins' USE-flag with appropriate SRC_URI variable,
  and changes within src_unpack() and src_configure() functions;
- add src_prepare() section as there is no PATCHES array in ebuild
  with fix for nomacs-plugins intallation and search path.

Closes: https://bugs.gentoo.org/712918
