Comment out checks that are causing failures on ^/stable/11, post-r337133

Some usr.bin/procstat code has not been MFCed to ^/stable/11 for command line
handling, and unfortunately, r337133 (which was MFCed as r337542) relies on
that support.

Comment out the checks and add a pointer to the PR for code archaeology and
to cause future potential parties to verify changes when backporting them.

This is a direct commit to ^/stable/11
