Hi Guix!

I've prepared several patches to improve the rust builds. These changes will
require a full bootstrap, as well as rebuilding icecat, so it may be worthwhile
to merge this into staging first.

The changes include:
* Update the `generate-checksums` function in cargo-utils to not require a
directory parameter (sha256sum can't support directories. We were previously
passing in "/dev/null" as an argument, so now that's assumed internally)
* Delete the install logs and manifests generated as part of the build since
the ordering of their contents can be nondeterministic
* Updated all source definitions to delete extra files/tools that are already
present in guix (e.g. deleting any llvm/clang/jemalloc sources). See below
for a reduction in the source derivations
* Updated rust to 1.34.1

Thanks!

Looks good to me, so I've adjusted a few commit messages and then pushed
to guix master.
(Icecat had no current substitute on the build machines anyway)
