utils: Add 'invoke/quiet'.
* gnu/build/bootloader.scm (G_): Remove. (open-pipe-with-stderr, invoke/quiet): Move to... * guix/build/utils.scm: ... here. Use 'let-values' instead of 'define-values' because Guile 2.0 (the bootstrap Guile) doesn't know about 'define-values'. * po/guix/POTFILES.in: Remove gnu/build/bootloader.scm, and add guix/build/utils.scm. * tests/build-utils.scm: Remove import of (gnu build bootloader).master
