build: update restore regexp in roachtest AWS suite

In cockroachdb#98259, the concept of `Low` memory per vCPU was introduced in
roachtest's `ClusterSpec`. That setting is currently only supported in
GCE; if a test that uses that setting is run on any other cloud,
roachtest will panic.

The only roachtest using the low-memory setting is currently a restore
test that is meant to run on GCE. However, the check for the appropriate
cloud is done by that test during runtime (necessarily so), meaning a
cluster will need to be created for the check to happen. By that
point, the test runner will panic due to the unsupported memory
setting.

In the long term, we want to support ways for roachtests to indicate
supported clouds outside the `Run` function (some context in cockroachdb#96655).
For now, to stop a panic from happening in roachtest nightly runs on
AWS, we update the regexp used to choose tests to run on AWS. We
leverage the fact that `restore` tests include the cloud they are
supposed to run in their name.

Epic: none

Release note: None
