Kernel: Make O_RDONLY non-zero

Browse source 
Sergey suggested that having a non-zero O_RDONLY would make some things
less confusing, and it seems like he's right about that.

We can now easily check read/write permissions separately instead of
dancing around with the bits.

This patch also fixes unveil() validation for O_RDWR which previously
forgot to check for "r" permission.
