Subject: init: INITRAMFS_PRESERVE_MTIME should depend on BLK_DEV_INITRD

[ Upstream commit 74792608606a525a0e0df7e8d48acd8000561389 ]

INITRAMFS_PRESERVE_MTIME is only used in init/initramfs.c and
init/initramfs_test.c.  Hence add a dependency on BLK_DEV_INITRD, to
prevent asking the user about this feature when configuring a kernel
without initramfs support.

Fixes: 1274aea127b2e8c9 ("initramfs: add INITRAMFS_PRESERVE_MTIME Kconfig option")
