Subject: [PATCH net-next v2] net/tcp_sigpool: Enable compile-testing

Since commit 37a183d3b7cdb873 ("tcp: Convert tcp-md5 to use MD5 library
instead of crypto_ahash"), TCP_SIGPOOL is only selected by TCP_AO.
However, the latter depends on 64BIT, so tcp_sigpool can no longer be
built on 32-bit platforms at all.

Improve compile coverage on 32-bit by allowing the user to enable
TCP_SIGPOOL when compile-testing.  Add a dependency on CRYPTO, which is
always fulfilled when selected by TCP_AO.

One remaining oddity is that TCP_SIGPOOL has always been a tristate
symbol, while all users that select it have always been boolean symbols.
I kept that as-is, as it builds fine as a module.

v2:
  - Add Reviewed-by.
