debugger: reduce scope of eslint disable comment

Current code masks setInterval and setTimeout with promisified versions.
This can be confusing to read and causes lint errors. Replace masking
with use of pSetInterval and pSetTimeout instead.

Move disabling of lint rule from entire file to the one remaining line
(after the above changes) that still needs it.
