Revert "perf symbols: Fix mismatched declarations for elf_getphdrnum"

This reverts commit f785f2357673d520a0b7b468973cdd197f336494.

We have a test to check if elf_getphdrnum() is present, so, if it fails,
we'll get:

[acme@rhel5 linux]$ cat /tmp/build/perf/feature/test-libelf-getphdrnum.make.output
cc1: warnings being treated as errors
test-libelf-getphdrnum.c: In function âmainâ:
test-libelf-getphdrnum.c:7: warning: implicit declaration of function âelf_getphdrnumâ
[acme@rhel5 linux]$

And this block will not be compiled:

#ifndef HAVE_ELF_GETPHDRNUM_SUPPORT
static int elf_getphdrnum(Elf *elf, size_t *dst)
...
#endif

So, if elf_getphdrnum() is being defined somewhere, there is a problem
with the test that is not detecting that function, go fix it.
