[Buildroot] [PATCH 7/9] package/pure-ftpd: add optional dependency to libxcrypt

[Bernd Kuhls <bernd@kuhls.net>]

When glibc was bumped to version 2.39 in commit
b5680f53d60acf8ff6010082f873438a39bd5d97 it removed the deprecated
libcrypt support.

As glibc's libcrypt was providing pure-ftpd's libcrypt dependency this
broke the pure-ftpd build using glibc version 2.39.

To fix this select the libxcrypt dependency to pure-ftpd when using a
glibc toolchain and add the dependency if selected.

Fixes:
