Make sure name matching occurs before name transformation.

The commit 9c194c99 altered that order.

* src/list.c (transform_stat_info): New function.  Split off from
decode_header.
(read_and): Call transform_stat_info right before do_something,
and after deciding if we should proceed with this member name,
so that name matching occurs before name transformation.

* tests/extrac17.at: New file.
* tests/Makefile.am (TESTSUITE_AT): Add extrac17.at
* tests/testsuite.at: Include extrac17.at.

+# Description: Tar 1.24 changed the ordering of name matching and
+# name transformation so that the former saw already transformed
+# file names (see commit 9c194c99 and exclude06.at).  This reverted
+# ordering made it impossible to match file names in certain cases.
+# In particular, the testcase below would not extract anything.
