selftests/ftrace: Add test case for a symbol in a module without module name

Browse Source 
Add a test case for probing on a symbol in a module without module name.
When probing on a symbol in a module, ftrace accepts both the syntax that
<MODNAME>:<SYMBOL> and <SYMBOL>. Current test case only checks the former
syntax. This adds a test for the latter one.
