PATCH v2 1/2 crypto: mark algs allowed in fips mode

Set the fips_allowed flag in testmgr.c's alg_test_descs[] for algs that are allowed to be used when in fips mode.

One caveat: des isn't actually allowed anymore, but des (and thus also ecb(des)) has to be permitted, because disallowing them results in des3_ede being unable to properly register (see des module init func).

Also, crc32 isn't technically on the fips approved list, but I think it gets used in various places that necessitate it being allowed.

This list is based on
http://csrc.nist.gov/groups/STM/cavp/index.html

Important note: allowed/approved here does NOT mean "validated", just that its an alg that *could* be validated.

Resending with properly updated patch v2 tag.
