Python_jll: Avoid linking to libcrypt.so.1 on glibc systems.

Equivalent of #4879.

Fixes:

Hmm, I'm still seeing:

tim@taurus /tmp/lib$ ldd libpython3.8.so
	linux-vdso.so.1 => linux-vdso.so.1 (0x00007ffc8e5cc000)
	libcrypt.so.1 => /usr/lib/libcrypt.so.1 (0x00007ff73c822000)

@giordano Any thoughts?

The problem is that we use an old glibc, which has a libcrypt.so which is ABI-incompatible with more modern glibcs. I don't have a good solution, apart from waiting the day we'll be able to choose the libc version

Edit: ok, the question was why this still links to libcrypt.so. I don't know, but probably there was something else in the build system pulling it in?
