Use a memcmp for the expected symbol name.

I believe that g++ does not guarantee what a particular symbol name will be. Thus, in g++ 11.4.0 (what is in Ubuntu 22.04), the symbol name here ended with "#2", while in g++ 13.2.0 (what is in Ubuntu 24.04), the symbol name ends with "#1". Given that we can't guarantee this, just search for the first part of the name up to the number, which should be good enough for this test. Signed-off-by: Chris Lalancette <[email protected]>
