Adriaan de Groot ec0fe2ccd3 Modules: Improve error reporting
- [initcpio] remove superfluous inner function
 - [initcpio] catch errors from mkinitcpio itself and report them in a nice
   readable format.

 - Save translators the effort of doing a dozen messages
   with just the name of the module changed. All of these modules
   bail out on bad configurations with a meaningful message.
   - [initcpiocfg]
   - [fstab]
   - [initramfscfg]
   - [localecfg]
   - [luksbootkeyfile]
   - [luksopenswaphookcfg]

 - [machineid] Warn on bad config. It's conceivable that this is run
   with an empty rootMountPoint (i.e. "") to modify the running system,
   so only bail on None.
