Makefile.inc: Enable -Wtype-limits
This patch enables -Wtype-limits for the whole repository, which
disallows checking for a condition that must be always true or always
false based on type width (e.g. checking whether an unsigned variable is
negative or whether a 32-bit integer is larger than 4G). This helps
avoid easy to make and hard to find (because they often only affect
error paths) mistakes like
size_t size = fmap_read_area(...);
if (size < 0)
die("If only the compiler could've told me to use ssize_t instead");
