perf tools: Remove hardcoded include paths for elfutils
This change removes the use of hardcoded absolute "/usr/include/elfutils" paths
from the perf build. The problem with hardcoded paths is that it prevents them
from being overridden by $prefix or by -I in CFLAGS (e.g., for cross-compiling
purposes).
Instead, just include the "elfutils/" subdirectory as a relative path when
files are needed from that directory.
Tested by building perf:
- Cross-compiled for ARM on x86_64
- Built natively on x86_64
- Built on x86_64 with /usr/include/elfutils moved to another location
and manually included in CFLAGS
