guix/build/gnu-build-system.scm (reset-gzip-timestamps): Ensure gzip
files are writable before resetting their timestamps.
---

There have been a number of instances of packages having to add their own phase
before 'reset-gzip-timestamps to make the gzip files writable--perhaps the gnu
build system can take care of this itself? WDYT?
