Bug#994741: regression tests: skipped vs failed

[<ian_bruce@mail.ru>]

The Inkscape v1.1 build fails on amd64, because of a regression test
called "text-gzipped-svg-glyph", which can be found here:

https://sources.debian.org/src/inkscape/1.1-1/testfiles/rendering_tests/text-gzipped-svg-glyph.svg/

from the build log:


            Start 301: render_text-glyphs-vertical
    301/303 Test #301: render_text-glyphs-vertical ........   Passed    2.25 sec
            Start 302: render_test-powerstroke-join
    302/303 Test #302: render_test-powerstroke-join .......   Passed    0.55 sec
            Start 303: render_text-gzipped-svg-glyph
    303/303 Test #303: render_text-gzipped-svg-glyph ......***Failed    0.26 sec

    text-gzipped-svg-glyph FAILED
    text-gzipped-svg-glyph-large SKIPPED

    99% tests passed, 1 tests failed out of 303


On i386, the build succeeds, apparently because this test does not run
at all:


            Start 301: render_text-glyphs-vertical
    301/302 Test #301: render_text-glyphs-vertical ........   Passed    2.65 sec
            Start 302: render_test-powerstroke-join
    302/302 Test #302: render_test-powerstroke-join .......   Passed    0.94 sec

    100% tests passed, 0 tests failed out of 302


If this test is not required on i386 (and presumably other architectures
where the build succeeds), then it shouldn't be required on amd64, either.

This discrepancy needs to be investigated.
