[PATCH] gawk: disable persistent memory by default due to licensing

[<Randy.MacLeod@windriver.com>]

From: Randy MacLeod <Randy.MacLeod@windriver.com>

In gawk-5.2, a feature that allows gawk to preserve memory between runs:
   https://www.gnu.org/software/gawk/manual/html_node/Persistent-Memory.html
was added. The files that implement this, support/pma.[ch], are licensed
under the AGPL which some entities perfer to avoid. Force people to knowingly
opt into using this feature and license.

Also add AGPL to the license to the summary.

Signed-off-by: Randy MacLeod <Randy.MacLeod@windriver.com>
