nongnu: steam: Use LD_LIBRARY_PATH instead of glibc-for-fhs.

* nongnu/packages/steam-client.scm (steam): Use wrap-program.
(glibc-for-fhs, fhs-ld.so.conf, ld.so.conf->ld.so.cache): Remove.
(make-internal-script): Remove references to ld.so.conf and ld.so.cache

-;;; We must re-enable ldconfig in glibc for Steam to prefer our system libraries
-;;; over Steam's runtime (which has incompatible Mesa and gcc).  This is because
-;;; the Steam script located at
-;;; Steam/ubuntu12_32/steam-runtime/run.sh
-;;; overrides $LD_LIBRARY_PATH with the following order enforced:
-
-;;; * "Pinned" libraries (pinned_libs_{32,64} directories containing symlinks)
-;;; * Output from `/sbin/ldconfig -XNv`
-;;; * steam-runtime paths
-;;; * Existing $LD_LIBRARY_PATH
-
-;;; Without ldconfig Steam's runtime will have priority over system libraries as
-;;; well as any paths supplied to Steam in the initial $LD_LIBRARY_PATH.
-;;; "Pinned" library directories are created after installation, so we can't
-;;; use those either.
-
-;;; Disabling Steam's runtime is another solution, however that will add over
-;;; 80 additional dependencies (see commit: @a12f42e6)
