compel/x86/compat: pack ucontext_ia32

Browse Source 
As I've united k_rtsigset_t between native and compat ucontext's,
it's 8-bytes aligned now. We don't care about align of this as
we fill it always with memcpy()/memset(0).
So after those changes, ucontext_ia32 has received new padding
between uc_mcontext and uc_sigmask (4 bytes to align to 8-byte sized
sigmask). Because of this, mask of blocked signals was restored
with shift (wrongly).
Fixes: signalfd00, file_attr tests.
