[OE-core] [PATCH 4/4] initramfs-framework: support dropping into shell on failure

[Patrick Ohly]

When the init_fatal_sh boot parameter is present (i.e. used without
value) and a fatal problem occurs inside the initramfs-module, a shell
will be started instead of looping forever.

Useful for debugging.

Interestingly enough, the code was already indented to support such an
if check...
