Subject: [PATCH] libostree: Link with libgpg-error for gpg_strerror_r API

With f461c02bb55bf2853a3b81ed5c8618040ab54e98 use of gpg_strerror_r
was added this symbol comes from libgpg-error however, therefore its
needed to add -lgpg-error to cmdline to resolve this symbol especially
with gold and lld linker. Fixes

aarch64-yoe-linux-ld.lld: error: undefined reference due to --no-allow-shlib-undefined: gpg_strerror_r
