gnu: gcc: Use the system zlib.

Browse source 
* gnu/packages/gcc.scm (gcc-4.7) <configure-flags>: Pass
'--with-system-zlib'.
* gnu/packages/commencement.scm (gcc-boot0)[arguments]: Remove
'--with-system-zlib' from the configure flags.
* gnu/packages/commencement.scm (zlib-final): New variable.
(gcc-final)[arguments]: Add ZLIB-FINAL to #:allowed-references.
Pass -L and -Wl,-rpath for zlib in LDFLAGS, as a configure flag.
[inputs]: Add LD-WRAPPER-BOOT3 and ZLIB-FINAL.
