[PATCH] tests/qemu-iotests/183: Fix timeout issue when running tests in parallel

[Thomas Huth <thuth@redhat.com>]

When running "make check-block SPEED=slow -j$(nproc)", the test 183
fails due to the very low default timeout value since the system is
quite loaded and thus slower in this case. We need a much higher
value when running tests in parallel, so let's try to detect this
situation by looking for "-j..." in the MAKEFLAGS environment variable.

 PS: Yeah, I know, this is a little bit ugly ... if someone has a better
 idea how to fix this, please let me know.
