Make sure osl_getTempDirURL result doesn't end with / also on unx

This is consistent with what osl_getTempDirURL does on Windows
This is a blind attempt to fix a part of a failure reported on IRC:

/lode/dev/core/sal/qa/osl/file/osl_File.cxx:486: Assertion
Test name: osl_FileBase::getAbsoluteFileURL::getAbsoluteFileURL_001_1
equality assertion failed
- Expected: file:///var/folders/tj/jl7sh26124n4b94tm541m6xr0000gn/T//relative/file1
- Actual  : file:///private/var/folders/tj/jl7sh26124n4b94tm541m6xr0000gn/T/relative/file1
- Assumption is wrong: ResultURL is not equal to expected URL

That "//" in Expected might be because user's TMPDIR ends with /.
