Subject: [PATCH v2] libc/time: Move internal newlib tz-structs to local.h

As discussed in GCC bug 97088
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97088), parameters in
prototypes of library functions should use reserved names, or no name
at all.

This patch moves the internal struct __tzrule_struct from the public
API to the internal headerfile newlib/libc/time/local.h.
