fix macos CI test, add SQLites to coatjava build

[baltzell]

• Just remove reliance on CVMFS from github CI
• Add https://code.jlab.org/hallb/clas12/ccdbrcdb-sqlite for git-lfs storage of CCDB/RCDB SQLite files
• Add SQLite to the build script defaults (another 500 MB), add --nosqlite option

[c-dilks]

build-coatjava.sh now downloads the SQLite files by default, which could be out of date with respect to the "official" databases. However, these downloaded SQLite files are only used if $CCDB_CONNECTION or $RCDB_CONNECTION point to them (as you do in the CI here); otherwise, the databases that are used by default remain unchanged.

Do I understand that correctly?

[c-dilks]

Could we have a more descriptive PR title (for the release notes)?

[baltzell]

Yes, the SQLite snapshots are now included by default, but only used if one figures out how to set $CCDB/RCDB_CONNECTION to point to them.
