Bug 696126 (2): PCL/XPS should (sort of) ignore COMPILE_INITS (for now)

As the PCL and XPS exes *must* have the icc profiles available in a romfs, they
will paretially ignore the COMPILE_INITS setting, and always use a rom file
system for the ICC profiles. COMPILE_INITS=0 will cause PCL to not include
it's fonts in the romfs.

This means always including the romfs I/O code in the graphics library, then
building an empty romfs into Ghostscript for COMPILE_INITS=0, and the romfs i/o
will now return gs_error_unregistered from its file_status method if
the empty romfs is found (identified by gs_romfs_buildtime being zero).

No cluster differences.
