Use dev_t for device id (st_dev) from stat in setup_git_directory_gently()
The original declaration was int, which seems to cause trouble on my machine. It causes spurious "filesystem boundary" errors when running the testsuite. The cause seems to be $ stat -c%d . 2147549952 which is too large for a 32-bit int type. Using the correct type, dev_t, solves the issue. (Because I'm paranoid and forgetful, I checked -- yes, Unix v7 had dev_t.) Other uses of st_dev seem to be reasonably safe. fill_stat_cache_info truncates it to an 'unsigned int', but that value seems to be used only to validate the cache, and only if USE_STDEV is defined.
