run_net_test.sh: fix UML --readonly flag
Without this you end up with r=... instead of ubdar=... and:
Failed to initialize ubd device 0 :Couldn't determine size of device's file
VFS: Cannot open root device "98:0" or unknown-block(98,0): error -6
Please append a correct "root=" boot option; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(98,0)
Aborted
