Merge branch 'bc/archive-pax-header-mode'

Implementations of "tar" that do not understand an extended pax
header would extract the contents of it in a regular file; make
sure the permission bits of this file follows the same tar.umask
configuration setting.

* bc/archive-pax-header-mode:
archive: honor tar.umask even for pax headers
