Remove obsolete cast

The upstream timezone code uses a bool variable as an array subscript.
Back when PostgreSQL's bool was char, this would have caused a warning
from gcc -Wchar-subscripts, which is included in -Wall.  But this has
been obsolete since probably commit d26a810ebf9, but certainly since
bool is now the C standard bool.  So we can remove this deviation from
the upstream code, to make future code merges simpler.
