[contrib] Fix rom-o-matic git version number issues
Fixes issue in which git version number is not displayed on startup
when iPXE is built through rom-o-matic.
Remove special characters from filename generated by rom-o-matic (so
that you get "ipxe-1.0.0+c3b4-undionly.kkpxe" instead of
"ipxe-1.0.0+ (c3b4)-undionly.kkpxe")
