bitbake: cache: Remove invalid symlink for bb_cache.dat

Browse Source 
The bb_cache.dat might be an invalid symlink when error happens, then
os.path.exists(symlink) would return False for it, the invalid symlink
wouldn't be removed and os.symlink can't update it any more.

Use os.path.islink(symlink) can fix the problem.

(Bitbake rev: 1387d7b9ee3f270488f89b29f36f9f240e44accc)
