CppunitTest_sw_txt{export,import} failing now

[Dan Horák <dan@xxxxxxxx>]

Hi,

seems that probably after
https://cgit.freedesktop.org/libreoffice/core/commit/?id=85852ad0d96bfd71413aef94edc1b6e2e6052e1a
(or some other change merged during yesterday) the
CppunitTest_sw_txt{export,import} tests are failing now in our CI with
system fonts being used.

running under gdb reveals

(gdb) p rPattern.maTargetName 
$1 = "DejaVu Sans"
(gdb) p rPattern.maSearchName 
$2 = "Droid Sans Fallback"

but the system has dejavu-sans-fonts.noarch installed, so not sure
what's going on.


	Thanks,
