[PATCH 0/1] MR2157: ntdll/unix: Init the trap handler.

[eric pouech (＠epo)]

Otherwise we get nested exceptions on linux on any breakpoint in
a multi-arch wow64 (AMD64) configuration, running a 32bit debuggee.

With this patch, winetest kernel32:debugger runs to the end (it times
out without), yet spitting a couple of failures (that don't exist in
old wow64 configuration).

failure of linux32 pipeline is
```
msg.c:19191: Test succeeded inside todo block: WaitForSingleObject failed, ret:0
msg.c:19215: Test succeeded inside todo block: wrong status 00000000
```
which is a known sporadic failure (see https://bugs.winehq.org//show_bug.cgi?id=54037)
