Gracefully handle missing libcrypt.so.1 in standalone python builds

[jdstrand]

Once #26010 is fixed, we should gracefully handle missing libcrypt.so.1. This isn't needed for python-build-standalone, but is when influxdb is compiled with older glibc.

It is probably fine to simple Depends on libxcrypt-compat in the deb/rpm packaging. Will have to deal with tarball (perhaps instructions?)

Time estimation: blocked on #26010, then a few days for 'easy stuff', longer if try to do something more involved (strip out usage)
