Fix: Allow git worktree in version detection; drop svn, hg.

Browse Source 
If $ROOT_DIR is a linked working tree from git-worktree(1), then
$ROOT_DIR/.git is a regular file instead of a directory.  Allow this
when deciding whether to use git to detect OpenTTD's version.

Drop checks for svn and hg in config.lib, because findversion.sh
hasn't used svn nor hg since 192770e6da.
