hostapd: make "key" option optional if "wpa_psk_file" is provided

Browse Source 
If an existing "wpa_psk_file" is passed to hostapd, the "key" option may
be omitted.

While we're at it, also improve the passphrase length checking to ensure
that it is either exactly 64 bytes or 8 to 63 bytes.

Fixes: FS#2689
