Bug 4539

The test in src/testsuite/systemtap.samples/transport.exp for
"transport fill staging buffer - relayfs" is consitently failing on ia64 and
x86_64 machines. The previous test in the file does a systemtap script, but has
no "-b". It passes. Looking at the relative sizes of the files:

The probe2.out is from the "staging buffer" (-b) version and the probe.out is
without that option. They generate a different amount of output:

$ ls -l *.out
-rw-r--r--  1 root root 679758 May 23 15:57 probe2.out
-rw-r--r--  1 root root 678950 May 23 15:56 probe.out

Martin says that the systemtap.samples/transport.exp is redundant. The
systemtap.printf tests have finer grained testing. Probably should remove
systemtap.samples/transport.exp.
