mimic-iv/buildmimic/sqlite/import.py: replace strip()

`strip()` removes any of the given characters from both the start and
end of a string: https://docs.python.org/3/library/stdtypes.html#str.strip
For a filename "chartevents.csv.gz" the resulting tablename currently is
"hartevent" where it should be "chartevents".

    'chartevents'.strip('.gz').strip('.csv').lower()

Instead, strip the suffixes manually to derive the tablename from the
filename.

Later, we could use `removesuffix()`, which is available from Python 3.9
onwards: https://docs.python.org/3/library/stdtypes.html#str.removesuffix
