Backported improved error checking in install.py

[micheles]

For the future, if we will remove another tool now install.py will exit with an error and we will see the problem in the installation tests. Backport of #10774. Tested with openquake.taxonomy (the removed wheel) and we get

ERROR: Could not find a version that satisfies the requirement openquake.taxonomy (from versions: none)
ERROR: No matching distribution found for openquake.taxonomy
Compiling python/numba modules
The engine was installed successfully.
Command '['/home/michele/oq-engine/oq23/bin/python3', '-m', 'pip', 'install',
'--find-links', 'https://wheelhouse.openquake.org/py/standalone/latest/',
'openquake.taxonomy']' returned non-zero exit status 1.:
could not install openquake.taxonomy

Also, skipped tests of OQImpact that cannot work since we regenerated the exposure.hdf5 file.
