innobackupex fails when --user, --port or --socket is set

[kazuho]

Hello,

Thank you for all your works. While I was evaluating xtrabacku, I
noticted that innobackupex seems fails when either of the options --
user, --port, or --socket is being set, since the options are appended
to the arguments passed to mysql client after "--". Here is the patch
to solve the problem.
