recordmcount.pl: Add support for __fentry__
With gcc 4.6.0 the -mfentry feature places the function profiling call at the start of the function. When this is used, the call is to __fentry__ and not mcount. This is required for Ksplice as the C version of recordmcount doesn't insert section symbols for the __mcount_loc section so we fall back to the perl version. Based on 48bb5dc6cd9d30fe0d594947563da1f8bd9abada (ftrace: Make recordmcount.c handle __fentry__).
