deb: avoid use of [[ in 'rules' file

It's not supported by posix shell, and apparently my build system uses that.

# By default we build a .deb where the native components are built with the
# current "default" version of py3 on the build machine. If you wish to build a
# .deb that has native components built for multiple versions of py3:
#
#   1. install python3.x and python3.x-dev for each version you want
#   2. set DEB_HG_MULTI_VERSION=1 or DEB_HG_PYTHON_VERSIONS in your environment
#      (if both are set, DEB_HG_PYTHON_VERSIONS has precedence)
#
# If you choose `DEB_HG_MULTI_VERSION=1`, it will build for every "supported"
# version of py3 that's installed on the build machine. This may not be equal to
# the actual versions that are installed, see the comment above where we set
# DEB_HG_PYTHON_VERSIONS below. If you choose to set `DEB_HG_PYTHON_VERSIONS`
# yourself, set it to a space-separated string of python version numbers, like:
#   DEB_HG_PYTHON_VERSIONS="3.7 3.8" make deb
DEB_HG_MULTI_VERSION?=0

# Set to 1 to make /usr/bin/hg a symlink to chg, and move hg to
# /usr/lib/mercurial/hg.

	# package, and this file is not dynamic and does not account for manual
	# installations, just the ones that would be installed by `python3-all`. This
