dirmngr: Replace no-strict-overflow pragma by wrapv pragma.
* dirmngr/dirmngr.c (time_for_housekeeping_p): Build with --fwrapv. Replace protecting macro.
I once replaced all JNLIB macros by GPGRT macros. However, I missed
to get this right for the push pragma test and used
instead of the correct
Now after fixing this it turned out that no-strict-overflow is not
anymore supported as oprimize pragma and thus I replaced that too
according to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58454 .
Tested with 32 bit Windows but the real test will be in 2038.
