haswell: only provide NRI-based ROMs in releases

release="n" is set in target.cfg on haswell build targets
that use mrc.bin

script/update/release exports LBMK_RELEASE="y"

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

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

export LBMK_RELEASE="y"
./build roms all

This would skip these ROM images. The native haswell raminit is
now stable enough in my testing, that I wish to delete the MRC-based
targets. This is in line with Libreboot's Binary Blob Reduction Policy,
which states: if a blob can be avoided, it should be avoided.

The problem is that users often run the inject script in *lbmk* from
Git, instead of from the src release archive. I forsee some users
running this on modern lbmk with older release images. If the mrc-based
target isn't there, the user may use an NRI-based target name, and
think it works; they will insert without MRC. I foresaw this ages
ago, which is why Caleb and I ensured that the script checks hashes,
and hashes are included in releases.

Therefore: for the time being, keep the MRC-based configs in lbmk
but do not include images for them in releases. This can be done
indefinitely, but I'll probably remove those configs entirely at
some point.

On the following boards, Libreboot now will *only* provide NRI-based
ROM images for the following machines:

* Dell OptiPlex 9020 SFF
* Dell OptiPlex 9020 MT
* Lenovo ThinkPad T440p
* Lenovo ThinkPad W541/W540

I now recommend exclusive use of NRI-based images, on Haswell
hardware. It's stable enough in my testing, and now supports S3.
