George T Kramer 557fb493ca Make full file creation for directories thread-safe ...

When running many instances of swupd_make_fullfiles in parallel, the
read end of the pipe between the tar's for creating the full file of a
directory becomes reused.  The observed behavior of this is
swupd_make_fullfiles hangs indefinitely with the expected tar reader
missing.  The corresponding tar writer is not killed with SIGPIPE because
there is at least one reader still for the pipe, swupd_make_fullfiles.
First forking from swupd_make_fullfiles, creating the pipe, and then
fork-and-exec'ing for each tar ensures that pipe and file descriptor
management is contained for the directory rename in question and cannot
be reused by other directory renames.
