perf tools: elf_sym__is_function() should accept "zero" sized functions
Asm routines that end up having size equal to zero are not really zero sized, and as now we do kernel_maps__fixup_sym_end, at least for kernel routines this gets fixed. A similar fixup needs to be done for the userspace bits as well, but as this fixup started only because in /proc/kallsyms we don't have the end address nor the function size, it appeared here first.
