Subject: gnu: bash: Use the bootstrap Guile in 'url-fetch/reset-patch-level'.

Fixes <http://bugs.gnu.org/25775>.
Reported by Sirgazil, Ricardo Wurmus, Andy Wingo, and others.

* guix/download.scm (in-band-download): Always use GUILE.  This reverts
9f05908fb1e3707cae593d94688748294717a546.
* gnu/packages/bash.scm (url-fetch/reset-patch-level): Remove #:guile.
Pass %BOOTSTRAP-GUILE as #:guile to 'url-fetch'.  Remove #:guile-for-build
argument in 'gexp->derivation' call.
