[dak/master] daklib/checks.py: lintian check should not try to validate signatures

[Ansgar Burchardt <ansgar@debian.org>]

By default dpkg-source -x requires a valid signature, but uses different
keyrings than configured in dak. So this check can fail for signatures dak has
just verified as valid a bit earlier.

With this patch lintian will pass --no-check to dpkg-source to skip signature
(and checksum) verification.
