[PATCH] t0300-credentials: Word around a solaris /bin/sh bug

[Ben Walton <bwalton@artsci.utoronto.ca>]

Solaris' /bin/sh was making the IFS setting permanent instead of
temporary when using it to slurp in credentials in the generated
'dump' script of the 'setup helper scripts' test in t0300-credentials.

The stderr file that was being compared to expected-stderr contained the
following stray line from the credential helper run:

warning: invalid credential line: username foo

To avoid this bug, capture the original IFS and force it to be reset
after its use is no longer required.  For now, this is lighter weight
than altering which shell these scripts use as their shebang.
