Yes, I see that s6lockd-helper is in libexec; it won't be found.
I don't see s6-rc-oneshot-run. I assume that's in the separate s6rc
project, which I haven't installed.

In my bash scripts, which do need to be runtime-relocatable, since they're
designed to be run directly from a git checkout, I always have something
akin to:

HERE=$(dirname $(readlink -f $0))

Certainly readlink -f isn't a cheap operation, but dirname is a simple
string manipulation.
This does seem to work in the general case, and I feel sure I could come up
with something that's both quite efficient and correct in the edge cases if
I spent some time on the problem.

Oh, definitely. But it's *so close* to fitting!
