happrox.c:24:10: fatal error: 'pgm.h' file not found
The netpbm update from r451378 moved netpbm headers from include/ to
include/netpbm/, but gts looks for them in include/ only.
While here also clean up the port a little bit:
- Remove NETPBM_DESC since it's already in bsd.options.desc.mk
- Disable netpbm via an autoconf variable instead of patching
configure
