Subject: [PATCH] libquota: don't include system quota.h header

Don't use the system <sys/quota.h> header in mkquota.c, since there
is a local e2fsprogs version of quota.h that is already included and
has the desired quota constants, and avoids symbol conflicts with the
system <sys/quota.h> on other platforms (in particular OSX).
