Simplify lib-src version printing

* lib-src/Makefile.in (etags_cflags): Remove.
All uses replaced by a simple ‘-o $@’.
(ebrowse${EXEEXT}, emacsclient${EXEEXT}, emacsclientw${EXEEXT}):
Omit -DVERSION= option.
* lib-src/ebrowse.c (VERSION):
* lib-src/emacsclient.c (VERSION):
* lib-src/etags.c (EMACS_NAME, VERSION): Remove.
All uses replaced by PACKAGE_NAME and PACKAGE_VERSION.
* lib-src/ebrowse.c (version):
* lib-src/etags.c (print_version):
Use fputs to output the version info, since that’s fputs_unlocked.
* lib-src/etags.c (PROGRAM_NAME): New macro.
(print_version): Use it.
