debuginfo path

[Wenji Huang]

Hi,

The commit 921d61030221bc5ff27f8d63d3fa30e93f659484 made the debuginfo 
path could be specified with absolute path.

But one question, How about relative path, which it will begin with?

And the update in debugpath.exp

[...]
  set test "debugpath-good"

-spawn env SYSTEMTAP_DEBUGINFO_PATH=:/usr/lib/debug:build stap -e "probe 
kernel.function(\"sys_open\") {}" -p2

+set uname [exec /bin/uname -r]

+spawn env SYSTEMTAP_DEBUGINFO_PATH=/lib/modules/$uname/build stap -e 
"probe kernel.function(\"sys_open\") {}" -p2
[...]

I think we need to cover the installed kernel-debuginfo case which will 
put vmlinux under /usr/lib/debug/lib/modules/`uname -r`/
