sys-devel/mold: new revision sans "GNU gold" in --version.

The new mold-1.0.1-r1 includes upstream commit cea6a569afa5 which
removes the string "GNU gold" from mold's --version string. This is
necessary on Gentoo to prevent false positives from tc-ld-is-gold() in
the toolchain-funcs eclass.

Closes: https://bugs.gentoo.org/831478

+Subject: [PATCH] [ELF] Remove "GNU gold" from the --version string
+
+That substring was introduced in de7ba9014f9d9d70b9173c4bfac6c3433186ba49
+to appease Gentoo's dev-libs/jansson-2.13.1-r1 package. But I think I
+shouldn't done that from the beginning to avoid the sitaution of the
+"User-Agent" string of the web browser, which everybody claims they
+are Mozilla, AppleWebKit, Chrome and Safari simultaneously.
