Get commit SHA and date with JGit

In order to get the SHA and date we used to run shell scripts and parse
the output of `git` commands. On Windows we even ran a batch file that
looked for `bash.exe` and then ran the shell script in bash.

Using JGit should be more robust than the old Rube Goldberg
implementation. The values produced are the same, except for the time
zone. Previously the timestamp was formatted with the local timezone,
now we use UTC.
