Subject: [PATCH] Don't use file timestamp in cache filename
Every file in the nix store has a timestamp of "1", meaning that the
filename would remain constant even when changing zoneminder versions.
This would mean that newer versions would use the existing symlink to an
older version of the source file. We replace SRC_HASH in nix with a
hash of the source used to build zoneminder to ensure this filename is
unique.
