    testing: avoid false warning
    
    When FOLKS_BACKEND_PATH is set to the build dirs during testing, the
    "content type of '%s' appears to be '%s' which looks suspicious. Have
    you installed shared-mime-info?" warning gets triggered repeatedly,
    because these dirs contain all kinds of files (executables, compiler
    dependency files, etc.) which are not expected in the normal install
    location.
    
    This is annoying when running a test with "make <test>.gdb" because
    gdb stops on a glib trace point for each warning. Therefore disable
    the warning when FOLKS_BACKEND_PATH is set. Extending the whitelist
    has the drawback that it might not catch all files that can appear
    there in the future.
