tests/qemu-iotests: Mark 182 as Linux-only

Running test 182 on FreeBSD fails with this error message in the output:

 +warning: File lock requested but OFD locking syscall is unavailable, falling back to POSIX file locks
 +Due to the implementation, locks can be lost unexpectedly.

OFD locks seem to be only available on Linux, so let's mark this
test as Linux-only to silence the failure.
