Use straight quotes in lib-src diagnostics

These auxiliary programs can’t use Emacs’s text-quoting-style,
and it’s too much trouble to redo that mechanism by hand.
So just use straight quotes for now.
* lib-src/ebrowse.c (main):
* lib-src/emacsclient.c (decode_options, main):
* lib-src/etags.c (Ada_help, default_C_help, Cplusplus_help)
(Forth_help, HTML_help, Lisp_help, Makefile_help, Objc_help)
(Perl_help, PHP_help, Python_help, Scheme_help, TeX_help, auto_help)
(none_help, print_language_names, print_help, add_regex)
(suggest_asking_for_help):
* lib-src/make-docfile.c (write_c_args, scan_c_stream):
Use straight quotes in diagnostics.
