avr32: Fix sigaltstack behaviour
A signal handler should be able to change the signal stack used for the next signal by altering the ucontext_t passed as a parameter to the handler. This does not currently work on avr32 since it doesn't update the in-kernel signal context from the ucontext_t upon signal handler return. Fix it by adding a call to do_sigaltstack() from sys_rt_sigreturn(), bringing it in line with most other architectures.
