contrib: gpg-error: Backport a patch to fix building with -fno-common

GCC 10 and Clang 11 are switching to -fno-common by default,
which exposes bugs in libraries that don't use "extern" properly
for variable declarations. Backport a libgpg-error patch (upstream
commit 21dd885eecdee13da1689519e2fc50fcf64f6ef2) that fixes
this issue.
