Subject: [PATCH] Move sigreturn parser to libstrace

All architectures have rt_sigreturn, but only old ones also have
sigreturn.  Since not all architectures need a parser of sigreturn
syscall, remove the warning and move the parser to libstrace.

* Makefile.am (strace_SOURCES): Move sigreturn.c ...
(libstrace_a_SOURCES): ... here.
* linux/arch_sigreturn.c: Remove warning.
