mkinitcpio: ensure ERR trap propagates to install_modules

Without this flag set, errors in install_modules are ignored, and
mkinitcpio potentially exits without complaining about build problems
when foolish people run out of disk (presumably after using /tmp as a
build directory).

Fixes FS#35037.
