tools/mtd-utils: include sysmacros.h explicitly

glibc is moving to remove the include of sys/sysmacros.h from
sys/types.h, and some distros have done this early. Other libcs may
already lack this include. Include sysmacros.h explicitly.

Fixes: FS#1015

+Subject: [PATCH mtd-utils] include sys/sysmacros.h for major/minor/makedev
+
+These functions have always been defined in sys/sysmacros.h under
+Linux C libraries.  For some, including sys/types.h implicitly
+includes that as well, but glibc wants to deprecate that, and some
+others already have.  Include the header explicitly for the funcs.
