test_libvirt:LibvirtUtilsTestCase.test_get_fs_info fails on Mac OS X

[Lorin Hochstein]

test_libvirt:LibvirtUtilsTestCase.test_get_fs_info fails on Mac OS X because its "df" program doesn't support the -B flag.

$ ./run_tests.sh test_libvirt:LibvirtUtilsTestCase.test_get_fs_info --nologcapture

Note that you can't set a blocksize of 1 with df on OS X at all:

$ BLOCKSIZE=1 df /tmp
df: minimum blocksize is 512
