[Bug tapsets/11160] New: syscall.sigaction32 decoding $act argument incorrectly

["dsmith at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

On a 64-bit system, there are 64-bit and 32-bit versions of the sigaction system
call.

The syscall tapset wrapper for sysaction, 'syscall.sigaction', uses the
'_struct_sigaction_u' auxiliary function to decode the '$act' pointer back into
a string like 'SIG_IGN' or 'SIG_DFL'.

The syscall tapset wrapper for sysaction32, 'syscall.sigaction32', doesn't use
the '_struct_sigaction32_u' auxiliary function to decode the '$act' pointer. 
Even if it used that function, on rawhide kernels (2.6.32.2-15.fc13.x86_64),
that function doesn't decode the argument correctly.  (The hard-coded 'struct
sigaction32' may be a culprit.)
