s3:trusts_utils: use a password length of 120 for machine accounts
This is important when we change the machine password against
an RODC that proxies the request to an RWDC.
An RODC using NetrServerPasswordSet2() to proxy PasswordUpdateForward via
NetrLogonSendToSam() ignores a return of NT_STATUS_INVALID_PARAMETER
and reports NT_STATUS_OK as result of NetrServerPasswordSet2().
This hopefully found the last hole in our very robust machine account
password handling logic inside of trust_pw_change().
The lesson is: try to be as identical to how windows works as possible,
everything else may use is untested code paths on Windows.
A similar problem was fixed by this commit:

provision: Decrease the length of random machine passwords
The current length of 128-255 UTF-16 characters currently causes
generation of crypt() passwords to typically fail. This commit
decreases the length to 120 UTF-16 characters, which is the same as
that used by Windows.
