nettle: fix ptest failure

Remove dlopen-test.patch which originally used
to fix the test dlopen-test, but autually the
patch didn't resolve the issue as dlopen-test.patch
supposes the file /usr/lib/libnettle.so exists.
Instead deploy ${D}${PTEST_PATH}/libnettle.so to
fix the dlopen-test failure.

Update the initialization for the salt to fix
below Segmentation fault and also nettle-pbkdf2-test
failure.
