gnu: glibc: Really disable 'ldconfig' and /etc/ld.so.cache.

Browse source 
* gnu/packages/base.scm (glibc): Add 'snippet' to set use_ldconfig=no.
  Remove "glibc-no-ld-so-cache.patch"; that patch would still build
  'ldconfig', and ld.so would still contain ld.so.cache-related code,
  and would look for info in /etc/etc/ld.so.cache (sic).
* gnu/packages/patches/glibc-no-ld-so-cache.patch: Remove.
* gnu-system.am (dist_patch_DATA): Adjust accordingly.

Disable attempts to use the system-wide /etc/ld.so.cache. This is
required on LFS distros to avoid loading the distro's libc.so instead
of ours.
Patch from Nixpkgs. Idea by Eelco Dolstra, initial patch by Jack
Cummings, minor fixups by Shea Levy.
