x86/ftrace: Rename mcount_64.S to ftrace_64.S

Browse Source 
With the advent of -mfentry that uses the new "fentry" hook over mcount,
the mcount name is obsolete. Having the code file that ftrace hooks into
called "mcount*.S" is rather misleading. Rename it to ftrace_64.S and
remove the file name reference.
