package/git: use pkg-config to get ssl dependencies

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/test/autobuild/run/instance-2/output/host/sparc-buildroot-linux-uclibc/sysroot/usr/lib/libssl.a(ssl_cert.o): In function `CRYPTO_DOWN_REF':
/home/test/autobuild/run/instance-2/output/build/libopenssl-1.1.1a/include/internal/refcount.h:50: undefined reference to `__atomic_fetch_sub_4'

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

To fix this issue, use pkg-config to retrieve openssl dependencies
including atomic library, these dependencies must be passed to
LIB_4_CRYPTO IN GIT_MAKE_OPTS
