qtest/migration/rdma: Enforce RLIMIT_MEMLOCK >= 128MB requirement
Ensure successful migration over RDMA by verifying that RLIMIT_MEMLOCK is
set to at least 128MB. This allocation is necessary due to the requirement
to pin significant portions of guest memory, typically exceeding 100MB
in this test, while the remainder is transmitted as compressed zero pages.
Otherwise, it will fail with:
stderr:
qemu-system-x86_64: cannot get rkey
qemu-system-x86_64: error while loading state section id 2(ram)
qemu-system-x86_64: load of migration failed: Operation not permitted
qemu-system-x86_64: rdma migration: recv polling control error!
qemu-system-x86_64: RDMA is in an error state waiting migration to abort!
qemu-system-x86_64: failed to save SaveStateEntry with id(name): 2(ram): -1
qemu-system-x86_64: Channel error: Operation not permitted
