mkinitramfs:include libgcc_s in initramfs

The new version 2 of cryptsetup requires libgcc_s.so to be installed at
decrypt time, or the following error message will occur:

  libgcc_s.so.1 must be installed for pthread_cancel to work

Note that this only affects luks containers using the new version 2
spec. Version 1 containers use a different process that does not require
libgcc_s.
