Simplify SVG_DISABLE_FONT_EMBEDDING check

Environment variables are used as a source for bootstrap variables anyway.
Consistently consider SVG_DISABLE_FONT_EMBEDDING to be enabled if the bootstrap
variable is present, regardless of its value.

No need to tset it in CppunitTest_sd_import_tests, as it only affects SvgExport.
(However, there is currently no test of svg export in
CppunitTests_sd_export_tests, either; it was last disabled with
925907767c "disable sd's regression test again"
and subsequently removed with f5dbe0eaba "Usage of
XShapeDumper in Impress added.")
