runtime: remove the mlock hack in Go 1.15

The resolution to #35777 was to mlock the top of stack on "affected" kernels. But then it was discovered that major distros use kernels that appear by the version number to be affected but are actually patched (#37436).

It may be a bitch to do and contrary to Go best practices, but an "alert" (nag?) mode that notifies users that the kernel they run under needs a patch, or even better, gives them the ability to check if their kernel needs attention may be the only politically correct answer here.

Something that can easily be removed once the user has attended to it. Or, perhaps better, something they can add as part of the installation and drop as soon as possible.

Lucio.
