The above solutions (binding to an existing C library or os.execute a
command-line utility) are good ones.

For completeness, I'll mention that this would also be possible in
pure Lua, though with much more work.  The underlying DEFLATE
algorithm, used by zip/gzip has been implemented in [1], at least for
decompression.  The compression half could also be written if one is
so inclined.  bzip is not that much different.
