[librsvg/librsvg-2.50] Do not allow builds to fail

[Federico Mena Quintero <federico src gnome org>]

commit b887674dc09517a5c844d5b803980ba3371097fa
Author: Sven Neumann <sven svenfoo org>

    Do not allow builds to fail
    
    Make the tests more tolerant for some builds by setting the
    RSVG_TEST_TOLERANCE variable, but do not allow builds to fail.
    
    This should catch build errors and closes #579.
