perf symbols: Fix mismatched declarations for elf_getphdrnum

When HAVE_ELF_GETPHDRNUM_SUPPORT is false we trip on this problem:

    CC       /tmp/build/perf/util/symbol-elf.o
  util/symbol-elf.c:41:12: error: static declaration of ‘elf_getphdrnum’ follows non-static declaration
   static int elf_getphdrnum(Elf *elf, size_t *dst)
            ^
  In file included from util/symbol.h:19:0,
                   from util/symbol-elf.c:8:
  /usr/include/libelf.h:206:12: note: previous declaration of ‘elf_getphdrnum’ was here
   extern int elf_getphdrnum (Elf *__elf, size_t *__dst);
            ^
    MKDIR    /tmp/build/perf/bench/

  make[3]: *** [/tmp/build/perf/util/symbol-elf.o] Error 1

Fix it.
