    nettle-ptest: fix a failing test
    
    This patch changes the result of the nettle dlopen-test
    from FAIL to PASS. The test used to fail because the test could not
    find and load libnettle.so.
    This patch fixes this by using absolute path instead of relative.
    
    This was the only test out of 88 that used to fail.

+Replace relative path of libnettle.so with absolute path so the test
+program can find it.
+Relative paths are not suitable, as the folder strucure for ptest
+is different from the one expected by the nettle testsuite.
