Fix gdb.base/attach-twice.c build on NetBSD
Add a fallback definition of PTRACE_ATTACH that is an alias of
PT_ATTACH. Change the 4th argument of ptrace(2) to 0 as it is
compatible with void * (Linux) and int (NetBSD) arguments.
Include <sys/types.h> for <sys/ptrace.h>.
gdb/testsuite/ChangeLog:
* gdb.base/attach-twice.c: Include "sys/types.h".
(PTRACE_ATTACH): Add fallback definition.
(main): Pass `0' to the 4th argument of `ptrace'.
