t0050: appease --chain-lint

Some of the symlink tests check an either-or case using the
"||". This is not wrong, but fools --chain-lint into
thinking the &&-chain is broken (in fact, there is no &&
chain here).

We can solve this by wrapping the "||" inside a {} block.
This is a bit more verbose, but this construct is rare, and
the {} block helps call attention to it.
