dtc: Remove some small bashisms from test scripts

[David Gibson]

Some of the helper scripts used to run testcases contain some
constructs that are bashisms.  Or at least which don't work on dash,
the minimal shell used as /bin/sh on recent Ubuntu systems.

This patch removes these constructs so that the testsuite will pass
"out of the box" on systems where /bin/sh is dash.
