guix: consolidate glibc & gcc packages
Summary:
Refactor our glibc 2.28 to be a single 'package', and avoid the use of
package-with-extra-configure-variable. This also lets us drop the
enable_werror workaround, and just use --disable-werror directly.
Employ the same workaround as the Guix glibc, to avoid a "permission
denied" failure during build:
