TOMOYO: Avoid race when retrying "file execute" permission check.
There was a race window that the pathname which is subjected to "file execute" permission check when retrying via supervisor's decision because the pathname was recalculated upon retry. Though, there is an inevitable race window even without supervisor, for we have to calculate the symbolic link's pathname from "struct linux_binprm"->filename rather than from "struct linux_binprm"->file because we cannot back calculate the symbolic link's pathname from the dereferenced pathname.
