databases/mongodb4: Narow destructive-interference-size workaround

Previously --param=destructive-interference-size=64 was added on
aarch64 to work around a static assert (somehow related to -mtune and
possible ABI stability), but this is only recognized by newer gcc
(probably >= 12, but definitely 10 does not).

Limit the workaround to aarch64, NetBSD, and 10.99.x for now, making
the package build again on NetBSD 10 aarch64, in theory keeping it
buildable on NetBSD current aarch64.  This removes the workaround for
not-NetBSD aarch64 (but we don't have a report of it being needed).
