Ensure supported version of hypothesis is available

Ensure supported version of hypothesis is available

On FIPS-enabled platforms, we need to ensure a minimal version of
hypothesis which no longer uses MD5. This doesn't need to be enforced
for other platforms.

Move the import magic to a utility module to avoid copy-pasting the
boilerplate code around.
