package/sysrepo: link with libatomic when needed

Browse source 
On some architectures, atomic binutils are provided by the libatomic
library from gcc. Linking with libatomic is therefore necessary,
otherwise the build fails with:

/home/buildroot/autobuild/instance-2/output-1/host/opt/ext-toolchain/bin/../lib/gcc/sparc-buildroot-linux-uclibc/7.4.0/../../../../sparc-buildroot-linux-uclibc/bin/ld: libsysrepo.so.0.7.8: undefined reference to `__atomic_fetch_add_4'

This is often for example the case on sparcv8 32 bit.
