cmd/internal/bootstrap_test: update TestExperimentToolID for Go 1.21
This test is configured to run only when explicitly requested due to
being costly. Apply two updates so it can run on the toolchain today:
- overlay GOROOT/lib for zoneinfo.zip (similarly to CL 462279)
- stop expecting framepointer to be listed in the GOEXPERIMENT
section of the compiler version (see CL 49252 and CL 249857)
I checked if by now there's another test that would report a problem
if the fix made in CL 186200 had regressed. Running all.bash locally
with GO_TEST_SHORT=0 GO_BUILDER_NAME=darwin-arm64-longtest passed ok,
while this manual test did catch the problem.
Also simplify the test implementation while here so it's less different
from TestRepeatBootstrap.
For #33091.
