[PATCH] meson: src: Fix DESTDIR handling while creating dirs

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka at siemens.com>

If the target path contains a link with an absolute path (e.g.
/var/run -> /run), makedirs will target the wrong location. Resolve the
path first, then append DESTDIR again if needed.
