common.sh: exclude all of /build/share

A /build/share/constants.json is needed so components can compile policy
files at build time.  We don't need this file to end up on the board.
Per review request I'm masking all of /build/share.

BUG=None
TEST=Local build with compiling changes.  Verified files get compiled
but the constants.json don't end up on the board.
