tests: python executable path should always be globbed
Although this is coming in under the guise of consistency, part of the
desire for this is that at least as part of the official Solaris builds,
we build with a versioned python interpreter, such as "python2.7", which
doesn't match "*python".
# Extract version number into 4 parts, some of which may be empty:
#
# version: the numeric part of the most recent tag. Will always look like 1.3.
#
# type: if an rc build, "rc", otherwise empty
#
# distance: the distance from the nearest tag, or empty if built from a tag
#
# node: the node|short hg was built from, or empty if built from a tag
