[tz] [PATCH] make check_white_space fix for leap-seconds.list

[Paul Eggert]

* Makefile (check_white_space): Allow trailing white space in
leap-seconds.list.  This file is maintained by NIST, and the
current version has trailing white space, and has a checksum
making it inadvisable for us to remove the trailing white space in
our copy.  Also, coalesce two 'grep' calls into one, and check for
weird white space characters anywhere, not just before line end.
