make-binaries: Don't link against libnsl

Don't let the erl_call binary (used by eturnalctl) link against
libnsl.so.1, which is no longer shipped by default on RedHat-based
distributions, and isn't actually needed:

| the GNU C Library has never required programs that use 'gethostbyname'
| to be linked with libnsl.

Other projects are running into the same issue and don't seem to have
better solutions so far, cf.:

AppImageCommunity/pkg2appimage#336
astral-sh/python-build-standalone#51

Fixes #19.
