t/t7006: ignore return status of shell's unset builtin

The unset builtin of Solaris's xpg4/sh returns non-zero if it is passed a
variable name which was not previously set.  Since the unset is not likely
to fail, ignore its return status, but add a semicolon as a clue that the
'&&' was deliberately left off.
