ci: 90 minutes for the iOS unit suite, 60 for the UI suite

The first run of this workflow died at exactly 30 minutes with "context
deadline exceeded", fifteen seconds past the vector gate and still inside
xcodebuild. 30 was chosen when the suite was 741 tests; the 0.32 merge makes
it 1289, and a cold `ci-build` compiles the app, its tests and the obfs4
package before any of them run.

pauls-imac has capacity 1, so ui-tests waits for unit-tests and then builds
from its own derived data; 60 covers that.
