tests: thrift: check for channel closure before throwing
Previously, the binary protocol variant of ThriftTest would fail
consistently in CI for `qemu_x86_64` with the message below.
```
E: failed to poll fds -1, -1: 1
```
Note: 1 corresponds to EPERM
The root cause of this is that we do not yet have support for
standard synchronization primitives in C++, and there is
slightly racey behaviour in thrift until we do have support
for standard synchronization primitives.
With the addition of dynamic thread stacks, conforming pthreads,
and some additional work in the toolchain area
(re gthr-posix.h), we should soon be able to enable proper
synchronization primitives.
This change is a temporary workaround but solves the
test failure (which would occur even when tests all passed).
