Philippe Mathieu-Daudé a9ee641bd4 linux-user/flatload: Take mmap_lock in load_flt_binary() 
load_flt_binary() calls load_flat_file() -> page_set_flags().

page_set_flags() must be called with the mmap_lock held,
otherwise it aborts:

  $ qemu-arm -L stm32/lib/ stm32/bin/busybox
  qemu-arm: ../accel/tcg/user-exec.c:505: page_set_flags: Assertion `have_mmap_lock()' failed.
  Aborted (core dumped)

Fix by taking the lock in load_flt_binary().

Fixes: fbd3c4cff6 ("linux-user/arm: Mark the commpage executable")
