selftests: timers: leap-a-day: Fix -w option and update usage comment

Commit 98b74e1f3104 ("kselftests: timers: leap-a-day: Change default
arguments to help test runs") replaced the -s option with -w and made
"wait for the leap second" the non-default behaviour, but it only
updated the switch/case handling. Two things were left inconsistent:

  - The getopt() option string still lists 's' instead of 'w', so
    passing -w is rejected as an invalid option and the new behaviour
    cannot be selected at all.

  - The file header comment still documents the removed -s option and
    an outdated default for -i.

Fix the getopt() string to accept 'w' (matching the existing case 'w':
handler) and update the header comment to describe -w, -t and the
current -i default.
