packagegroup-agl-core-devel: remove duplicate profiling tools

Remove perf and powertop from packagegroup-agl-core-devel since they
are already in packagegroup-core-tools-profile which gets pulled in
when agl-devel is used.  For perf in particular, this simplifies
avoiding dependencies on the kernel source being available when
building container images.
