I did, but nothing changed. I probably need to set an environment
variable.

After building and installing LTP, it's finding the file, but some of
the issues still exist:

ima_keys 1 TINFO: $TMPDIR is on tmpfs => run on loop device
ima_keys 1 TINFO: Formatting /dev/loop0 with ext3 extra opts=''
ima_keys 1 TINFO: verify key measurement for keyrings and templates specified in IMA policy
grep: Unmatched ( or \(
ima_keys 1 TPASS: specified keyrings were measured correctly
ima_keys 2 TINFO: verify measurement of certificate imported into a keyring
keyctl_session_to_parent: Operation not permitted
ima_keys 2 TPASS: logged certificate matches the original

IMA policy:
measure func=KEY_CHECK keyrings=.ima|.evm|.builtin_trusted_keys|.blacklist|key_import_test template=ima-buf
measure func=KEY_CHECK keyrings=key_import_test template=ima-buf
