tools/btdecode.sh: make grep overridable

Browse source 
This script seems to assume GNU grep, which is not commonly
available as "grep" on some platforms.  For examples, it's
more common to have it named "ggrep" on BSD-based systems
including macOS.

Ideally, I suppose we should avoid GNU dependencies like this
in general.  But I'm not motivated enough to rewrite this script
in a portable way today.

cf. https://www.gnu.org/software/grep/manual/grep.html#grep-Programs-1
