tdf#34171: check foreign lockfiles to tell who has locked document

MS Office (Word/Excel/PowerPoint) lockfiles are supported now.
Note that Excel does *not* create lockfiles for pre-OOXML files.

This changes osl_openFile implementation on Windows, to treat
osl_File_OpenFlag_NoLock to also include FILE_SHARE_DELETE flag
for CreateFileW. This is required to allow opening files created
with FILE_FLAG_DELETE_ON_CLOSE flag, such as Excel's owner files.
The shange should be consistent with the overall meaning of the
osl_File_OpenFlag_NoLock to not impose any locking constraints
to the file being opened.
