agetty: improve login(1) argv[]
* fix regression: missing username should not be reported (EPERM) if
-n/--skip-login is given and username is NULL.
* don't compose login options *string* if we can use argv *array* (the
string is necessary only for --login-options).
* don't overwrite --login-options by --autologin
The old code silently ignores login-options and "login -f <username>"
is always used.
The new code uses:
a) "login -f <username>" by default
b) "login <login-options>" for --login-options + --autologin
where for b) the username from "--autologin <username>" is used to
replace \u magic string in <login-options>.
* the \u could be used more than once in one login argv string, for
example: agetty --login-options "-o user=\\u,name=\\u --foo"
* the space in --login-options is correctly ignored, for example
agetty --login-options " hello world ".
