gnu: zip: Improve build process and install man pages in share/man.

* gnu/packages/zip.scm (zip): Eliminate custom configure phase which copied
  and patched the Makefile.  Instead add "-f" and "prefix" to make-flags, as
  well as "MANDIR".  Remove "generic_gcc" from the make-flags, so that it will
  not be passed during other phases involving 'make'.  Instead replace the
  'build' phase with one that specifies the "generic_gcc" target.
