Subject: scripts/gen_initramfs_list.sh: fix flags for initramfs LZ4 compression
LZ4 as implemented in the kernel differs from the default method now used
by the reference implementation of LZ4. Until the in-kernel method is
updated to support the new default, passing the legacy flag (-l) to the
compressor is necessary. Without this flag the kernel-generated,
LZ4-compressed initramfs is junk.
