[Bug translator/11772] New: listing_mode_vars are empty with debuginfoless SDT

[jistone at redhat dot com]

As noted in bug 11769 comment 1, we rely on derived_probe::getargs() to list the
available args, but uprobe_derived_probe doesn't know about SDT's debuginfoless
$arg1, $arg2.  (Nor $$name or $$provider, for that matter).  The args still work
in a normal script though.

$ stap -L 'process("stap").mark("*")'process("stap").mark("cache__add__module")
process("stap").mark("cache__add__source")
process("stap").mark("cache__clean")
process("stap").mark("cache__get")
process("stap").mark("pass0__end")
process("stap").mark("pass0__start")
process("stap").mark("pass1__end")
process("stap").mark("pass1a__start")
process("stap").mark("pass1b__start")
process("stap").mark("pass2__end")
process("stap").mark("pass2__start")
process("stap").mark("pass3__end")
process("stap").mark("pass3__start")
process("stap").mark("pass4__end")
process("stap").mark("pass4__start")
process("stap").mark("pass5__end")
process("stap").mark("pass5__start")
process("stap").mark("pass6__end")
process("stap").mark("pass6__start")
process("stap").mark("stap_system__complete")
process("stap").mark("stap_system__spawn")
process("stap").mark("stap_system__start")
