[PATCH] t1900: cover repo info path keys in non-default layouts

[Jialong Wang <jerrywang183@yahoo.com>]

Extend the path-key coverage in t1900 to exercise layouts where the
reported paths differ from a regular worktree.

Add comparisons against rev-parse for path.git-dir, path.common-dir,
and path.toplevel in a linked worktree and a repository created with
--separate-git-dir. Also cover path.git-dir with --path-format=relative
in the separate-git-dir case, and path.superproject-working-tree with
--path-format=relative in a submodule.
