Workaround VCL complextext failure on Win7 KVM QXL

My Windows 7 KVM QXL VM fails the bounding rect test with:

complextext.cxx:98 VclComplexTextTest::testArabic equality .. failed
- Expected: 71x14@(0,1)
- Actual  : 70x14@(1,1)

This doesn't happen using a SSHd on Cygwin64 based session.

Adding a SAL_DEBUG to WinSalGraphics::GetGlyphBoundRect shows many
different glyph rects, which - probably by pure chance - almost add
up to just a single pixel line missing on the left.

So this simply drops the first pixel column, if the bounding rect
starts with an offset. Works for me.
