Improve tar check if bsdtar is installed

Browse Source 
If bsdtar is installed, fix script error for tar version detection.

bsdtar does not provide all expected command line (long) options
like "--hard-dereference". To ensure compatibility, mark version
of tar as 'invalid' and trigger build of 'host-tar'.
