Remove HAVE_ERRNO_H
The `<errno.h>` header file is part of the standard C89 headers [1] and
on older systems there needed to be also a manual check if header is
present.
Since libgd requires at least C89 or greater, the `HAVE_ERRNO_H`
symbol defined by Autoconf in configure.ac [2], and Cmake build system
files can be removed and simplifed.
