permit excluding certain coreboot roms on releases

release="n" can be set in target.cfg on coreboot targets

script/update/release exports CBMK_RELEASE="y"

script/build/roms skips building a given target if release="n"
in target.cfg *and* CBMK_RELEASE="y"

you could also do the export yourself before running ./build roms,
for example:

export CBMK_RELEASE="y"
./build roms all

this will be used in subsequent revisions, to exclude certain
targets from the next canoeboot release.
