The scripts are not expected to work with locale-sensitive data,
and since unusual locales may let them go haywire, try to avoid
it by forcing locale to C at the beginning of the scripts.
* check_caveats: Export LC_ALL=C.
* reload_microcode: Likewise.
* update_ucode: Likewise.
* microcode_ctl.spec (Release): Bump to 3.
(%changelog): Mention it.
