crypto: ecrdsa - Fix module auto-load on add_key
Add module alias with the algorithm cra_name similar to what we have for
RSA-related and other algorithms.
The kernel attempts to modprobe asymmetric algorithms using the names
"crypto-$cra_name" and "crypto-$cra_name-all." However, since these
aliases are currently missing, the modules are not loaded. For instance,
when using the `add_key` function, the hash algorithm is typically
loaded automatically, but the asymmetric algorithm is not.
Steps to test:
1. Cert is generated usings ima-evm-utils test suite with
`gen-keys.sh`, example cert is provided below:
$ base64 -d >test-gost2012_512-A.cer <<EOF

EOF
2. Optionally, trace module requests with: trace-cmd stream -e module &
3. Trigger add_key call for the cert:
# keyctl padd asymmetric "" @u <test-gost2012_512-A.cer
939910969
# lsmod | head -3
