lib/string: change return types to match C standard
The return type of strspn and strcspn is supposed to be a size_t and not
a signed integer.
TEST=Now the openSIL code can be built with the coreboot headers without
needing to add '-Wno-builtin-declaration-mismatch' or
'-Wno-incompatible-library-redeclaration' to the cflags. Before the
build would error out with various 'mismatch in return type of built-in
function' errors.
