From google earth there seems to be a single track line that runs past
Drayton Park station on the east side at a higher level than the
moorgate line then disappears into its own tunnel further south. What
line is this?

I think it is the connection to Canonbury on the North London Line.
This used to carry some peak hour passenger trains into Broad Street.
I do not know if it is still in use.

It can be seen in the 1:50k map at

The Canonbury Curve, which connects Finsbury Park and the ECML to the
North London Line. It currently has no passenger service, though it is
used by freight and possibly some empty coaching stock.

There was a plan to use it to terminate the East London Line extension
at Finsbury Park (rather than H&I), but that would require 8 train
movements an hour on the flat across the entire NLL formation, so was
unsurprisingly dropped as a non-starter.

I saw an old picture once which appeared to be of the southern end of
the Canonbury Curve; it showed a four-track mainline heading west into
the left-hand upper corner of the photo, with a double-track flat
junction splitting from the right-hand pair of lines and curving away
into the right-hand upper corner of the photo.

Is there space at the southern end to construct a medium-speed
(30-40mph) flyover for down trains to Finsbury Park?

No:

It's all in steep-sided cutting in a dense residential area. The
tunnel mouth isn't far from the junction, and there are road
overbridges either side on the main line that would need rebuilding.

You'd want a flyover for both tracks because passenger trains need to
cross the NLL freight line (which is the northern of the three).
