commit f15d7114bbdd ("Documentation/watchdog: add timeout and ping rate
control to watchdog-test.c") used both atoi() and strtoul() for string
to integer conversion. As usage of atoi() is discouraged in newer code,
replace it with strtoul() for consistency.

Switch from manual argv[] parsing to getopt_long() argument processing.
This creates more readable code and allows easier feature addition.
This also fixes some segmentation faults introduced by
commit 1dbdcc810928 ("selftests: watchdog: accept multiple params on
command line"), when options -t or -p are not given the required value:
./watchdog-test -p 1 -t
./watchdog-test -t 1 -p
No changes are intended in the way watchdog-test interacts with the
kernel. The only noticible changes, tightly related to the addition
of getopt (and done for easier maintenance), are:
- help message has been reworked and migrated to a dedicated function.
- all short/long options and the help message are sorted alphabetically.
- all case statements inside the getopt loop are sorted alphabetically.
Fixes: 1dbdcc810928 ("selftests: watchdog: accept multiple params on command line")

Convert spaces to tabs for checkpatch compliance. Quick way to verify
this is by running `git show -w <commit-id>`, which returns an empty
commit body. No functional change intended.
