p7zip truncates password to 8 chars when entered from terminal vs command-line arg

[whorfin]

Observed with 7z and 7za from

 pkg:/compress/p7zip@16.2-151038.0

Basically, because Solaris nerfed getpass(), getpassphrase() should be called instead on Illumos.

Reported upstream:
https://sourceforge.net/p/p7zip/bugs/230/

This is rather insidious as it "self-consistent" - one thinks one is making encrypted archives with long passwords which can't be opened on eg Linux, or vice-versa, but which can be expanded only the system on which they were made. ..until one realizes one can open them on Linux by typing only 8 characters, but on Illumos, one must currently use the command-line-passed password form.

thank you for the report.
