Subject: [PATCH] redo-apenwarr: fix tests in sandboxed darwin

From https://github.com/apenwarr/redo/blob/7f00abc36be15f398fa3ecf9f4e5283509c34a00/t/105-sympath/all.do#L16-L17 -
redo's testsuite uses /etc/passwd as a sample absolute-path dependency that won't change. Under darwin, this gets caught by sandboxing:

> do      t/105-sympath/all
> do        ../../../../../../private/etc/passwd
> do: ../../../../../../private/etc/passwd: no .do file (/nix/var/nix/builds/nix-15278-2435295101/source)

Fix tests by replacing /etc/passwd with another arbitrarily-chosen absolute path which we know we can read
