Subject: [PATCH 64/93] [plugin] add tmp_in_sysroot() method

Add a method that plugins can test to determine whether the
archive's temporary directory is inside sysroot. This is always
true when sysroot is '/'. When sysroot is a subdirectory of root
the temporary directory may be inaccessible from the chroot
namespace. Plugins can test this method to determine where to
write output.
