changes to zdump.c and zic.c invocations of is.* macros

[Arthur David Olson]

Below are proposed changes to zic.c and zdump.c to avoid compiler warnings
about invocations of the is.* macros, to meet standard requirements for calling
the macros, and to make the invocations consistent.

I plan to deal with gettext issues in the next round of changes.
