[arch-projects] [initscripts] [PATCH v2] Add fastboot support

[Lukas Fleischer]

This one adds support for the "/fastboot" file, as well as the
"fastboot" kernel command line parameter. If either of them is
specified, file system checks are skipped. The only exception is the
existence of "/forcefsck" or the "forcefsck" kernel parameter which have
precedence over fastboot.

Implements FS#26154.
