ci: Improve test_memory_mergeable_on stability

Browse Source 
The integration test test_memory_mergeable_on has been fairly unstable
for quite some time now. Because it can take some time for the VM to be
spawned and to be able to perform a correct measure of the PSS, this
commit simply increases the time before such measure is done.
This should return more accurate PSS results, which should help
stabilize the test.

Fixes #781
