Subject: [PATCH] stdenv: fix paxmark

On Linux, paxctl's setup hook should overwrite the paxmark stub, but the
stub is defined after the setup hooks are sourced, so the stub ends up
overwriting the real function.  The result is that paxmark fails to do
anything.  The fix is to define the stub before any setup hooks are
sourced.  Thanks to @vcunat for figuring this out.

Closes #15492
