strace: fix build against 5.15 kernel/kernel-headers

kernel 5.15 removed ipx.h from the uapi, but strace hasn't adjusted
its tests to the removal.

There is a WIP patch on the esyr/5.15 branch that solves the problem,
so we grab it here, adjust for context and fix our build problem.

When strace updates to 5.15, and we can bump our version and drop
this patch.

+Subject: [PATCH] Avoid relying on presence of ipx.h
+
+After Linux has broken UAPI in commit v5.15-rc1~157^2~207, it is well
+possible that neither kernel nor libc (such as musl, for example)
+provide IPX-related header.  Avoid relying on its presence
+in the strace's code and conditionalise the relevant checks in the tests.
+
+* configure.ac (AC_CHECK_HEADERS): Add linux/ipx.h.
+* src/net.c: Remove <netipx/ipx.h>/<linux/ipx.h> includes.
+* src/sockaddr.c: Likewise.
+(IPX_NODE_LEN): New macro constant.
+(struct sockaddr_ipx): New type definition.
+* src/xlat/sock_ipx_options.in (IPX_TYPE): Provide a fallback value.
+* tests/net-sockaddr.c [!HAVE_LINUX_IPX_H]: Do not include
+<linux/ipx.h>.
+[!HAVE_LINUX_IPX_H && HAVE_NETIPX_IPX_H]: Include <netipx/ipx.h>.
+[!(HAVE_LINUX_IPX_H || defined HAVE_NETIPX_IPX_H)]: Do not define
+check_ipx.
+[!(HAVE_LINUX_IPX_H || defined HAVE_NETIPX_IPX_H)] (main): Do not call
+check_ipx.
