netlabel: fix shift wrapping bug in netlbl_catmap_setlong()

[ Upstream commit b403643d154d15176b060b82f7fc605210033edd ]

There is a shift wrapping bug in this code on 32-bit architectures.
NETLBL_CATMAP_MAPTYPE is u64, bitmap is unsigned long.
Every second 32-bit word of catmap becomes corrupted.
