[PATCH] t0050: fix printf format strings for portability

[Jonathan Nieder <jrnieder@gmail.com>]

Unlike bash and ksh, dash passes through hexadecimal \xcc escapes.
So when run with dash, these tests *pass* (since '\xcc' is a perfectly
reasonable filename) but they are not testing what was intended.

Use octal escapes instead, in the spirit of v1.6.1-rc1~55^2
(2008-11-09).

Good point.  POSIX printf is not required to support \x escape
sequences.
