Philip Withnall c9619a4904 tests: Test pull behaviour when network timeouts occur
Extend test-pull-repeated.sh to test error 408 as well as error 500, to
ensure that the new retry-on-network-timeout code in ostree-repo-pull.c
correctly retries.

Rather than the 200 iterations needed for the error 500 tests, only do 5
iterations. The pull code internally does 5 retries (by default), which
means a full iteration count of 25. That seems to be sufficient to make
the tests reliably pass, in my testing — we can always bump it up to 200
/ 5 = 40 in future if needed (to put it in parity with the error 500
tests).
