KVM: selftests: memslot_perf_test: increase guest sync timeout

When memslot_perf_test is run nested, first iteration of test_memslot_rw_loop
testcase, sometimes takes more than 2 seconds due to build of shadow page tables.

Following iterations are fast.

To be on the safe side, bump the timeout to 10 seconds.
