commands: wd: add new -x option to inhibit all watchdogs
When booting after nv.autoboot=abort, barebox will drop to shell and
try to inhibit all watchdogs: If they can be disabled, they will be and
otherwise if autopoll support is compiled in, they will be periodically
fed. This is useful for development. For this to work though, barebox
needs an environment. Make watchdog_inhibit_all more accessible by
making it directly invocable with wd -x.
