Set kbas to be less restrictive on allowed filenamesbenbrown/remove-restrictions

ybd makes no attempt to escape filenames for the restrictions set by
kbas, thus certain chunks can end up being built every time.  Loosen
restrictions set by the kbas regex to fix such cases:

    [libdbus-c++] Starting upload
    [libdbus-c++] Artifact server problem: 400
    [libdbus-c++] Failed to upload libdbus-c++.joidja8
