Thomas Petazzoni 045651e253 libv4l: fix build on AArch64
AArch64 does not implement the SYS_open system call, but only the
SYS_openat system call, as should be done for all modern architectures
merged into the Linux kernel. This causes problems when building
libv4l 0.8.9, which are fixed by integrating an upstream patch,
available in a more recent version of libv4l. Backporting the patch is
preferred over bumping libv4l, as libv4l has a fairly large number of
reverse dependencies, and we don't want to break anything that close
to the release.

Note that this commit also renames the existing libv4l-largefile.patch
to libv4l-01-largefile.patch in order to comply with the Buildroot
patch naming scheme, and guarantee the order in which patches are
applied.

[PATCH] fixup lfs mismatch in preload libraries
Ensure that the lfs variants are not transparently used instead of the !lfs
ones so both can be wrapped, independently of any custom CFLAGS/CPPFLAGS.
