util/amdfwtool: Fix iteration of PSP firmwares 

Correct an oversight in the utility that attempts to match up eligible
PSP directory table entries with blob names passed on the command
line.  A 1:1 matchup of items shouldn't be assumed, so the i iterator
shouldn't be used to walk both lists.

This change has no effect on google/grunt (Family 15h Models 70h-7Fh),
but eliminates blank entries of all FF's on builds of amd/bettong
(F15h 60h-6Fh) and pcengines/apu2 (F16h 30h-3Fh).  Removal of entries
also affects the checksum accordingly.

TEST=Build before/after images for grunt, bettong, apu2, and diff
     hexdumps of the amdfw.rom files
