[arch-projects] [MKINITCPIO][PATCH 1/2] Fix printing of bash usage when asking for a bad hook

[Sebastien Luttringer]

before:
mkinitcpio -H sex
/sbin/mkinitcpio: line 105: /lib/initcpio/install/sex: No such file or directory
Help for hook 'sex':
GNU bash, version 4.2.10(2)-release (x86_64-unknown-linux-gnu)
These shell commands are defined internally.  Type `help' to see this list.

after:
mkinitcpio -H sex
No such hook: sex
