s-nail: Set VAL_MTA

Some build server may provide sendmail like /usr/lib/sendmail which
may result the VAL_MTA to be /usr/lib/sendmail during do_configure,
but the sendmail is actually /usr/sbin/sendmail on the target.

Fixes:
  # echo "invalide address email" | s-nail -s "test mail" -r test@test.com tester@test.com
  s-nail: Cannot start /usr/lib/sendmail: executable not found (adjust *mta* variable)
  /home/root/dead.letter 10/234
  s-nail: ... message not sent

  # which sendmail
  /usr/sbin/sendmail
