BUG/MINOR: tools: fix parsing "us" unit for timers

Commit c20ad0d8dbd1bb5707bbfe23632415c3062e046c (BUG/MINOR: tools:  make
parse_time_err() more strict on the timer validity) broke parsing the "us"
unit in timers. It caused `parse_time_err()` to return the string "s",
which indicates an error.

Now if the "u" is followed by an "s" we properly continue processing the
time instead of immediately failing.

This fixes #1209. It must be backported to all stable versions.
