Corrected the sky130.json file, which had a major problem caused by
accidentally duplicating a block of text, resulting in an invalid
JSON file.  Also:  Revised the JSON file format so that "commit" is
a block rather than a single key-value pair, and is contstructed
similarly to the "version" block, with an entry for each tool used
in the PDK build (currently magic and open_pdks), to provide a git
commit number for each.  This has to be done in conjunction with
the update of magic to version 8.3.273 to provide the "--commit"
command line option.
