gdbserver: fix format string warning in win32-low.cc

When compiling on Cygwin, we get:

      CXX    win32-low.o
    /home/smarchi/src/binutils-gdb/gdbserver/win32-low.cc: In function ‘int get_child_debug_event(DWORD*, target_waitstatus*)’:

`ptid.lwp ()` is a `long` value, so it indeed needs the `l` size modifier.
