Rather than parse /proc/keys directly to find out the ID of the keyring
that we're using, let keyctl do this for us. In order to do that we
need to have /proc available as /proc, so move it around before and
after working with keyctl.

${COREBASE}/LICENSE is not a valid license file. So it is recommended
to use '${COMMON_LICENSE_DIR}/MIT' for a MIT License file in
LIC_FILES_CHKSUM. This will become an error in the future.
