index: Correctly write entry mode

Browse Source 
The entry mode flags for an entry created from a path name were not
correctly written if the entry was a symlink. The st_mode of a statted
symlink is 0120777, however git requires the mode to read 0120000,
because it does not care about permissions of symlinks.

Introduce index_create_mode() that correctly writes the mode flags in
the form expected by git.
