[OE-core] [PATCH] perf: Remove CFLAGS and LDFLAGS override

[Otavio Salvador]

The kernel build system does the right thing here and we should stop
overriding it. This code has been added based on a change from
'meta-metro' layer, revision 9d698004137c1a888d40d6a4808d94afa22387e7,
without any information about what problem it fixes so I am reverting
it.

Using the CFLAGS makes it impossible for kernel build system to append
to it, thus making the build fail in various ways as:

|     CC /.../perf/1.0-r8/perf-1.0/perf.o
| In file included from builtin.h:4:0,
|                  from perf.c:9:
| util/util.h:74:24: fatal error: lk/debugfs.h: No such file or directory
|  #include <lk/debugfs.h>
|                         ^
| compilation terminated.
