[PATCH 3/5] libarchive: avoid dependency on e2fsprogs

[Saul Wold <sgw@linux.intel.com>]

From: Paul Eggleton <paul.eggleton@linux.intel.com>

libarchive's configure script looks for ext2fs/ext2_fs.h in order to use
some defines for file attributes support if present (but doesn't link to
any additional libraries.) There is no configure option to disable this,
and if e2fsprogs is rebuilding between do_configure and do_compile you
can currently get a failure. Because it doesn't need anything else from
e2fsprogs, and e2fsprogs isn't currently buildable for nativesdk anyway,
copy the headers in from e2fsprogs-native which we're likely to have
built already (and add it to DEPENDS just to be sure we have.)

Fixes [YOCTO #6268].

(From OE-Core master rev: ad754e46ad477acfbe7543187a5c38bc333b8612)
