Correct stack setup. This incorporates two changes:
1. The MI code in kern_exec.c will produce a mis-aligned stack if
sigcodesz is not a multiple of register_t. Fix this with a hammer.

2. C functions (like _start) write their parent LR to the parent's stack
frame. As such, the 48 bytes above the stack address, which used to
include argv, can be overwritten by garbage in certain circumstances. The
correct amount of stack padding is now applied.
