        PR26665: relayfs-on-procfs megapatch

Changes the way that capabilities are checked when compiling
a systemtap probe.

In our cross-build -> on target workflow, this results in a
mismatch between the systemtap configuration capabilities and
the kernel configuration.

The result is a compilation failure since the security
components are protected by two different #ifdef's, and they
can be out of sync. By protecting the include and callsite with
the same #ifdef, we ensure they are in sync and fix our
on target problem.

While this fix is oe-specific, a variant will be proposed
upstream once a deeper analsysis of other options has been
completed.
