initramfs: use vfs_stat/lstat directly
sys_newlstat is a system call implementation that is meant for user space, and that copies kernel-internal data structure to the user format, which is not needed for in-kernel users. Further, as we rearrange the system call implementation so we can extend it with 64-bit time_t, the prototype for sys_newlstat changes. This changes the initramfs code to use vfs_lstat directly, to get it out of the way of the time_t changes, and make it slightly more efficient in the process. Along the same lines we also replace sys_stat and sys_stat64 with vfs_stat.
