[Buildroot] [PATCH] fbgrab: explicitly build fbgrab target to workaround gzip issue

 > gzip reads default command line options from the environment variable GZIP.
 > The fbgrab Makefile internally also uses a GZIP make variable to know what
 > command to use to compress the manpage. Unfortunaly make will export the
 > value of this make variable to the environment if GZIP is already present in
 > the enviroment, confusing gzip (as 'gzip' isn't a valid command line argument).

 > This can either be triggered by users having GZIP set in their environment
 > (E.G.  for custom options), or by enabling BR2_REPRODUCIBLE, where we use
 > this feature to force the -n option (to not store name/timestamp) to gzip.

 > We don't really need to compress the manpage as it isn't installed anyway,
 > so work around the issue by only building the fbgrab application.
