[GSOC PATCH v2] t2003: modernize path existence checks using test helpers

["Burak Kaan Karaçay" <bkkaracay@gmail.com>]

The old style 'test -f' and 'test -d' checks are silent on failure,
which makes debugging difficult.

Replace them with the 'test_path_is_*' helpers which provide verbose
error messages when a test fails.

Thank you for the review.

Changes since v1:

- Fixed subject line.
- Split the command chain.
