Rework dlopen-test.patch to fix below
dlopen-test failure:
# cd /usr/lib64/nettle/ptest
# ./run-ptest
dlopen failed: /usr/lib/libnettle.so: cannot open shared object file: No such file or directory
./run-ptest: line 8: 7607 Aborted "./$f"
FAIL: dlopen-test
As the test dlopen-test depends on libnettle.so
which belongs to nettle-dev package, so add it
to rdepends of nettle-ptest.
