Mathieu Desnoyers 6f87493c3a selftests/rseq: Fix ppc32 offsets by using long rather than off_t
commit 26dc8a6d8e11552f3b797b5aafe01071ca32d692 upstream.

The semantic of off_t is for file offsets. We mean to use it as an
offset from a pointer. We really expect it to fit in a single register,
and not use a 64-bit type on 32-bit architectures.

Fix runtime issues on ppc32 where the offset is always 0 due to
inconsistency between the argument type (off_t -> 64-bit) and type
expected by the inline assembler (32-bit).
