process: disable building execve on IBM i

[abmusse]

The execve syscall does exist on IBM i but
it has caveats that make it not usable in Node.js context.

These changes disable building with execve like Windows does.

Fixes #57882

I ran test build on IBM i and looks like this test failed parallel.test-process-execve-validation

https://ci.nodejs.org/job/node-test-commit-ibmi/nodes=ibmi74-ppc64/1897/testReport/(root)/parallel/test_process_execve_validation/

I think I need to add to this condition for IBM i here:

node/lib/internal/process/per_thread.js

Lines 289 to 291 in 91d8a52

	} else if (process.platform === 'win32') {
	throw new ERR_FEATURE_UNAVAILABLE_ON_PLATFORM('process.execve');
	}
