tinylogin: fix segfault from crypt()

In glibc 2.17, crypt() now expects 2 valid chars for the seed or
it will error out and return a NULL. The tinylogin code took the
result from crypt directly into a strcmp() which caused a segfault

Tinylogin has been deperacted, busybox now has login support, I will
investigate using busybox login support for 1.5.

shadow: add patch to fix crypt: Invalid Argument

This patch came from Slackware and address a change in crypt()'s handling
of an invalid seed, which in the past returned an encrypted string and now
returns a NULL.

linux-firmware: make the main package depend on all sub-packages

Whilst splitting out specific large firmware blobs is a good move for space
saving, it makes installing "all the firmware" tricky.

Make linux-firmware depend on all of the separated packages so that installing
that pulls in all of the sub-packages.
