When applying a patch that adds an executable file, git apply ignores the core.fileMode setting (core.fileMode in git config specifies whether the executable bit on files in the working tree should be honored or not) resulting in warnings like:
warning: script.sh has type 100644, expected 100755
even when core.fileMode is set to false, which is undesired. This is extra true for systems like Windows.
Fix this by inferring the correct file mode from either the existing index entry, and when it is unavailable, assuming that the file mode was OK by pretending it had the mode that the preimage wants to see, when core.filemode is set to false. Add a test case that verifies the change and prevents future regression.
