[committed] Don't change directory in dwz-tests.exp

[Tom de Vries <tdevries@suse.de>]

Hi,

During execution of dwz-tests.exp, the current directory is changed.

When executing one more file dwz-tests-2.exp after dwz-tests.exp, the current
directory when entering dwz-tests-2.exp is the (changed) one at the exit of
dwz-tests.exp, while both .exp files expect to start with the same current
directory.

Fix this by resetting the current directory to its original value.

Committed as obvious.

Thanks,
- Tom
