homectl: fix typos in help text (#36279)

I noticed two small typos while reading the help text for homectl.  
The `-P` option is described as "Same as
--enforce-password-**password**=no" when the option's name is
`--enforce-password-policy`.
While checking the man page to check if the typo was also there, i
noticed another typo where `--enforce-password-policy=no` has 3 dashes
instead of 2 in the description for `-P`.
