linux: Enable kernel configs for SystemTap

Some of required kernel configs to use SystemTap are not enabled by
default. It is nessesary to rebuld and replace kernei before using it.
This commit will avoid it.

v2: Make the change conditional to 'agl-devel' and not apply in production.

Bug-AGL: SPEC-3360
