RFR: 8345234: Build system erroneously treats 32-bit x86 Zero as deprecated

[Aleksey Shipilev]

The checks added by [JDK-8344093](https://bugs.openjdk.org/browse/JDK-8344093) are apparently too broad: configuring `--with-jvm-variants=zero` says the port is deprecated, while it is actually not. I should have checked it with [JDK-8344093](https://bugs.openjdk.org/browse/JDK-8344093), mea culpa. I now see this issue while migrating my CIs to build x86-zero instead of x86-server.

Additional tests:
 - [x] Linux x86_32 server, configure fails by default
 - [x] Linux x86_32 server, configure passes with `--enable-deprecated-ports=yes`
 - [x] Linux x86_32 zero, configure passes by default
