Increase test timeouts for slow CI/build virtualization about cloudi

cat /sys/devices/system/clocksource/clocksource0/current_clocksource
cat /sys/devices/system/clocksource/clocksource0/available_clocksource

Will show kvm-clock for KVM pvclock (xen on AWS instance, with tsc,hpet,acpi_pm available, the typical options with a Linux installation, AWS EC2 VMs that use Nitro should have kvm-clock as the clocksource). May be good to get that data into code_status through some route.

erlang:system_info(os_monotonic_time_source).
erlang:system_info(os_system_time_source).

Currently provide the C call info. LXC container is currently the problem.

virt-what may be used to determine the virtualization and disable tests that require reasonable clock_gettime CLOCK_MONOTONIC return values, though it would need to be a build/test time dependency due to the GPL use:

Ok, with the --with-test-timeout and --with-long-test-timeout configure script arguments this problem is fixed.
