package/libbytesize: new package

Libbytesize is a small library providing a C "class" for working with
arbitrary big sizes in bytes.

The mdraid plugin for libblockdev depends on this package, which newer
versions of udisks require when building with the udisks daemon
enabled.

+Subject: [PATCH] remove msgcat dependency
+
+Gettext-tiny does not include the msgcat utility, which causes issues when
+building libbytesize for embedded systems, as many embedded systems do not
+build the full gettext, but instead use the gettext-tiny library.
+
+Because msgcat is not needed to build libbytesize, it's safe to remove the
+dependency.
