Makefile.SH: use standard tags file name for ctags

By default, vim only looks for a tags file literally called "tags" (or
"TAGS" if emacs compatibility is enabled). "Tags" won't be found with
default settings, at least on a case-sensitive file system. Also, remove
"--totals" to make the command less noisy.
