Subject: perf scripting: Avoid leaking the scripting_context variable

From: Arnaldo Carvalho de Melo <[email protected]>

commit cf346d5bd4b9d61656df2f72565c9b354ef3ca0d upstream.

Both register_perl_scripting() and register_python_scripting() allocate this variable, fix it by checking if it already was.
