mkfs.f2fs: set project quota by default for -g android for v4.14+
With this patch, "-g android" enables project quota only by default, if the
kernel is over v4.14. Otherwise, it enables usr/grp/proj all together.
1) -O quota : enables usr/grp
2) -O project_quota -O extra_attr : enabled prj
3) -O quota -O project_quota -O extra_attr : enables usr/grp/proj
4) -g android : enables proj (4.14+), usr/grp/proj (old kernel)
5) -g android -O project_quota -O extra_attr : enables usr/grp/proj
