.azurepipelines/templates: Increase run to shell timeout

Increase the CI agent timeout to boot to UEFI Shell from
1 minute to 2 minutes.  There have been a few cases where
the boot to shell in QEMU has not quite completed in 1
minute and it is failing the CI check and preventing a PR
from being merged.
