distro: glibc: Add a statically-linked Bash to $out/bin.

* distro/packages/base.scm (glibc): Pass `ac_cv_path_BASH_SHELL' in the
  configure flags.  During the `pre-configure' phase, copy the
  "static-bash" input to $out/bin, and change `system' and `popen' to
  use it instead of /bin/sh.  Add the "static-bash" input.
  Suggested by Shea Levy <shea@shealevy.com> and
  Lluís Batlle i Rossell <viric@viric.name>.
