crypto: testmgr - disallow RSA PKCS#1 SHA-1 sig algs in FIPS mode

When booted with fips=1, RSA signature generation using SHA-1 must not be
available.  However, pkcs1pad(rsa,sha1) can currently be instantiated
because it is not present in alg_test_descs; alg_test() falls through the
no_test path and succeeds, after which the algorithm appears in
/proc/crypto as fips-capable.

Add explicit alg_test_descs entries for pkcs1pad(rsa,sha1) and
pkcs1(rsa,sha1) without marking them fips_allowed, so they are treated as
not FIPS-allowed when fips=1 is enabled.

Include both names to cover kernels where RSA sign/verify is provided via
the pkcs1(...) signature template, while pkcs1pad(...) remains for the
traditional wrapper naming and/or RSAES operations.
