libcli/smb: add define SMB_ENCRYPTION_GSSAPI for CIFS encryption type

Add a define for the CIFS UNIX extensions encryption type. We store this
in smbXsrv_channel and use it in smbstatus for showing the
CIFS/SMB2/SMB3 encryption cipher used.

The SMB3 encryption cipher constants start at 1, carefully choosing the
highest available bit for the CIFS UNIX extensions encryption cipher
should avoid collisions and leaves room for many SMB3 ciphers in the
future.
