[Bug tapsets/11794] New: returnstr(fmt) needs to be replaced with return_str(fmt, $return)

[dsmith at redhat dot com]

Several tapsets (most notable the syscall tapsets) call returnstr(fmt) to get
the return value formatted as a string.  returnstr() calls _stp_returnval() to
poke around in the (architecture specific) registers to find the return value. 
We already have that information in $return.  So, whenever possible, we should
replace 'returnstr(fmt)' with 'return_str(fmt, $return)', which should produce
the exact same result.
