fix(pkgctl): avoid pacman db dependency checks during repo detection

By default the sync operation enables dependency checks during the
preparation of the transaction. This isn't necessary for the print
option, but is done nevertheless, which leads to issues for example
during soname dependency problems. The result is a none functional
automatic repo detection.

Fix this by explicitly disabling dependency version checks. We specify
this option twice to skip all dependency checks.

Fixes #189
