Hello,

    Set NetBSD xml syscall file name to syscalls/netbsd.xml

    The syscall literal names are not stable on NetBSD and can change
    once a syscall is versioned. Thus these names are internal to the
    system and in GDB mostly descriptive, not intended to be a stable
    interface with fixed names across GDB and NetBSD versions to track
    certain syscalls.

    gdb/ChangeLog:

            * nbsd-tdep.c: Include "xml-syscall.h".
            (nbsd_init_abi): Call `set_xml_syscall_file_name'.
