smb: client: allow creating symlinks via reparse points
Add support for creating symlinks via IO_REPARSE_TAG_SYMLINK reparse
points in SMB2+.
These are fully supported by most SMB servers and documented in
MS-FSCC. Also have the advantage of requiring fewer roundtrips as
their symlink targets can be parsed directly from CREATE responses on
STATUS_STOPPED_ON_SYMLINK errors.
