crypto: fips - make proc files report fips module name and version
FIPS 140-3 introduced a requirement for the FIPS module to return
information about itself, specifically a name and a version. These
values must match the values reported on FIPS certificates.
This patch adds two files to read a name and a version from:
/proc/sys/crypto/fips_name
/proc/sys/crypto/fips_version
v2: removed redundant parentheses in config entries.
v3: move FIPS_MODULE_* defines to fips.c where they are used.
v4: return utsrelease.h inclusion
