Use only POSIX conforming features of printf

This fixes 3 test failures on Solaris 10.

POSIX standardized printf, but the hex style \xHH sequences
aren't included in the standard. POSIX printf does understand
octal style \NNN sequences, though.

This should also work with shells where printf is a builtin (e.g.
on Lubuntu which probably uses dash).

Tested with xpg4-sh on Solaris 10 and bash/zsh/dash on Linux.
