[build] Include only one copy of each ROM in "make allroms"

mcb30 · mcb30 · commit 0579b8279cb9 · 2011-03-30T15:49:00.000+01:00
Each PCI ROM currently ends up appearing twice in the $(ROMS) list:
once under its designated name (e.g. "rtl8139.rom"), once under its
PCI IDs (e.g. "bin/10ec8139.rom").

Include only the latter of these in the $(ROMS) list, so that doing
"make allroms" will generate only one copy of each ROM.
