[Buildroot] [git commit branch/2025.02.x] package/x11r7/xapp_xdm: needs libxcrypt

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=af3e9238c70d2a3ff0886b2ea48f9436bb75da00
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2025.02.x

While doing a per-package build the package is failing to
compile with this error (gcc 13.x glibc toochain):
make[3]: Entering directory
'/home/wbx/buildroot-2025.02.3/output/build/xapp_xdm-1.1.14/xdm'   CC
session.o session.c:146:11: fatal error: crypt.h: No such file or
directory   146 | # include <crypt.h>       |           ^~~~~~~~~
compilation terminated.

Fix this error by providing the needed glibc dependencies.
