open-vm-tools: fix build w/ glibc-2.44

Failing Hydra build: https://hydra.nixos.org/build/344174037

This package builds fine on the base of this branch, so it's somehow
related to the glibc change, I'm just not understanding how.

Anyways, the issue is that `g_free` is a macro in glib (NOT glibc) and
was expanded in here leading to a syntax error. Removing this line
entirely fixes the issue for us.
