perf tools: Fix cross compile for ARM64

Currently when cross compiling perf tool for ARM64 on my x86 machine I
get this error:

arch/arm64/util/sym-handling.c:9:10: fatal error: gelf.h: No such file or directory
#include <gelf.h>

For the build, libelf is reported off:

Auto-detecting system features:
... libelf: [ OFF ]

Indeed, test-libelf is not built successfully:

more ./build/feature/test-libelf.make.output
test-libelf.c:2:10: fatal error: libelf.h: No such file or directory
#include <libelf.h>
compilation terminated.

I have no such problems natively compiling on ARM64, and I did not
previously have this issue for cross compiling. Fix by relocating the
gelf.h include.
