Install <xcrypt.h> and a symlink from libxcrypt.so to libcrypt.so.

This is needed as some configure scripts may look for symbols available
in libxcrypt.so.  For static libraries a corresponding symlink for the
archive file will be installed.

The installation of those compatibility files can be disabled by passing
the '--disable-xcrypt-compat-files' flag to the configure script.
