Too larger number in badkprobe test on 32 bits machine.

[Wenji Huang <wenji dot huang at oracle dot com>]

Hi,

The test systemtap.base/badkprobe.exp will fail on 32 bits machine.
[wjhuang@EL4U6-32bits testsuite]$ uname -mr
2.6.28 i686
[wjhuang@EL4U6-32bits testsuite]$ sudo runtest 
systemtap.base/badkprobe.exp --tool_opts install
...
Running ./systemtap.base/badkprobe.exp ...
FAIL: bad kprobe registration (eof)

                ===  Summary ===

# of unexpected failures        1

In fact, executing the stap script in the test case.
[wjhuang@EL4U6-32bits testsuite]$ sudo stap -g -w -vve 'probe 
kernel.statement(-1).absolute {} probe timer.s(1) { exit() }'

Seems "-1" is interpreted as 64-bit number and not appropriate for 32 
bits machine. Change to other number or update translate.cxx to perform 
explicitly truncation ?
