When we create temp files for downloading packs, we use a name
based on the current timestamp. There is no randomness in the
name, so we can have collisions in the same second.

Retry the temp pack names using a new "-" suffix to the
name before the ".temp".

This is a follow-up to #229.

Wow! We got a collision in the concurrent test suite even with the microsecond value in the basename.

as an alternative, we could encode the PID in the tempfile pathname.

These updates allow the gvfs-helper to be more resilient to concurrent pack downloads.

See microsoft/git#229 and microsoft/git#231 for more details.
