crypto: testmgr - Restore sha384 and hmac_sha384 drbgs in FIPS mode

Set .fips_allowed in the following drbg alg_test_desc structs.

drbg_nopr_hmac_sha384
drbg_nopr_sha384
drbg_pr_hmac_sha384
drbg_pr_sha384

The sha384 and hmac_sha384 DRBGs with and without prediction resistance
were disallowed in an early version of the FIPS 140-3 Implementation
Guidance document. Hence, the fips_allowed flag in struct alg_test_desc
pertaining to the affected DRBGs was unset. The IG has been withdrawn
and they are allowed again.

Furthermore, when the DRBGs are configured, /proc/crypto shows that
drbg_*pr_sha384 and drbg_*pr_hmac_sha384 are fips-approved ("fips: yes")
but because their self-tests are not run (a consequence of unsetting
the fips_allowed flag), the drbgs won't load successfully with the seeming
contradictory "fips: yes" in /proc/crypto.

This series contains a single patch that sets the fips_allowed flag in
the sha384-impacted DRBGs, which restores the ability to load them in
FIPS mode.
