[PATCH v3 2/7] merge-ort: drop unnecessary temporary in check_for_directory_rename()

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

check_for_directory_rename() had a weirdly coded check for whether a
strmap contained a certain key.  Replace the temporary variable and call
to strmap_get_entry() with the more natural strmap_contains() call.
