stop installing git-tar-tree link
When the built-in "git tar-tree" command (a thin wrapper around "git archive") was removed in 925ceccf (tar-tree: remove deprecated command, 2013-11-10), the build continued to install a non-functioning git-tar-tree command in gitexecdir by mistake: $ PATH=$(git --exec-path):$PATH $ git-tar-tree -h fatal: cannot handle tar-tree internally The list of links in gitexecdir is populated from BUILTIN_OBJS, which includes builtin/tar-tree.o to implement "git get-tar-commit-id". Rename the get-tar-commit-id source file to builtin/get-tar-commit-id.c to reflect its purpose and fix 'make install'.
