makepkg: Use read to parse status file during signature verification.
Instead of invoking grep multiple times, parse the status file once. This refactoring also changes the behvaiour when signature verification fails due to a missing public key: It is now an error instead of a warning. Signed-off-by: Allan McRae <allan@archlinux.org>
