From: Peter Maydell <peter.maydell@linaro.org>

We were defining TARGET_FS_IOC_GETFLAGS and TARGET_FS_IOC_SETFLAGS
using the host 'long' type in the size field, which meant that
they had the wrong values if the host and guest had different
sized longs. Switch to abi_long instead.

This fixes a bug where these ioctls don't work on 32-bit guests
on 64-bit hosts (and makes the LTP test 'setxattr03' pass
where it did not previously.)
