tools/gpgtar: Use the new exectool helper.

* tools/Makefile.am: gpgtar now requires neither npth nor libassuan.
* tools/gpgtar-create.c (gpgtar_create): Use the new 'sh-exectool'
helper.
* tools/gpgtar-extract.c (gpgtar_extract): Likewise.
* tools/gpgtar-list.c (gpgtar_list): Likewise.
* tools/gpgtar.c (main): Set default gpg program.  Drop the
initialization of npth and libassuan.
