Philip Withnall b1ebb72522 glocalfileoutputstream: Fix ETag check when replacing through a symlink 
Since commit 87e19535fe, the ETag check when writing out a file through
a symlink (following the symlink) has been incorrectly using the ETag
value of the symlink, rather than the target file. This is incorrect
because the ETag should represent the file content, not its metadata or
links to it.

Fix that, and add a unit test.
