#12103 - CI for FreeBSD (#12179)

* Ref #12103 - adds FreeBSD CI
* Fix getApplFreebsd - length of the string includes the null terminator byte, so minus 1 for result length
* Show last commit in setup task.
* Remove .git from repository URL
* Don't include noisy details showing last commit.
* Add FreeBSD build status badge
* Fix #12182 - disable tconsole on FreeBSD
* Disable tgetaddrinfo on FreebSD as getaddrinfo doesn't support the ICMP protocol.
* Install boehm-gc-threaded
* Use libgc-threaded.so on FreeBSD rather than libgc.so.
* Simplify build failure handling. Update alt text for CI badge.
* Disable test on FreeBSD
* Simplify build config

- use GNU make to build csources
- set PATH variable using the environment key
- remove modification of config to set CC as this is already set

* Install git which seems to be missing from current freebsd images
* Revert change to how path is set
* Add a comment explaining why the length is truncated
* Fix tconsole.
