package/heimdal: host package needs host-libxcrypt

The host-heimdal package has always needed a crypt library, but now
that libcrypt is no longer part of glibc, we're seeing build failures
on machines with recent host glibc versions. To fix this, we add
host-libxcrypt to the dependencies, and ensure host-heimdal links with
it.

Fixes:
