Change scanf/printf %hhx format strings to %x, because not every libc supports it.

In particular, the version of newlib distributed by Ubuntu is not
configured with --enable-newlib-io-c99-formats, and now includes guard
code that treats %hhx as an error, rather than silently interpreting it as
%hx. The net effect was to break hal_uuid_parse.

(Ironically, vfprintf.c does not (yet) include this guard code, but it's
probably only a matter of time, and it seemed expedient to change
hal_uuid_format at the same time.)
