Subject: [PATCH] Set xattrs after setting times

With Integrity Measurement Architecture (IMA) enabled in Linux
kernel the security.ima extended attribute gets overwritten
when setting times on a file with a futimens() call. So it's safer
to set xattrs after times.

Upstream-Status: Submitted [https://github.com/libarchive/libarchive/pull/664]
