pid: use ns_capable_noaudit() when determining net sysctl permissions

The capability check should not be audited since it is only being used
to determine the inode permissions. A failed check does not indicate a
violation of security policy but, when an LSM is enabled, a denial audit
message was being generated.

The denial audit message can either lead to the capability being
unnecessarily allowed in a security policy, or being silenced potentially
masking a legitimate capability check at a later point in time.

Similar to commit d6169b0206db ("net: Use ns_capable_noaudit() when
determining net sysctl permissions")
