 update inode flags for linux 4.5
 Linux 4.5 updated the list of inode flags including removing some existing
 flags. This patch fixes the resulting FTBFS by updating the flags list.

 fix test t0274a.sh on recent kernels
 As a result of fixing CVE-2015-8543, the behavior of creating a socket with an
 invalid protocol changed on recent kernels. Protocol numbers above 255 now
 return EINVAL. Fix the test by using a known illegal protocol and type
 combination which will fail with EPROTONOSUPPORT.

 only compile sysctl code if sysctl exists

 do not require fully defined struct ustat
 Fixes ustat related FTBFS on adm64. Since explain_errno_ustat does not write to
 the data argument, it's pointless to try and allocate any memory for it anyway.

 fix ftbfs on hppa - add handling of flags with multiple bits set
 On hppa the 'eventfd EINVAL' test was failing because the EFD_NONBLOCK was
 being incorrectly parsed. On hppa this flag sets two separate bits but the
 explain_parse_bits_print function does not handle this case. Fix by rewriting
 the algorithm to work on both cases. The access_modes table needed reordering
 to keep the old behavior there (this patch might change the ordering of some
 flags). Also handle a similar situation in explain_buffer_open_flags.
