archive: don't queue excluded directories

Reject directories with the attribute export-ignore already while
queuing them.  This prevents read_tree_recursive() from descending into
them and this avoids write_archive_entry() rejecting them later on,
which queue_or_write_archive_entry() is not prepared for.

Borrow the existing strbuf to build the full path to avoid string
copies and extra allocations; just make sure we restore the original
value before moving on.

Keep checking any other attributes in write_archive_entry() as before,
but avoid checking them twice.
