recipetool: create: support extracting name and version from build scripts
Some build systems (notably autotools) support declaring the name and
version of the program being built; since we need those for the recipe
we can attempt to extract them. It's a little fuzzy as they are often
omitted or may not be appropriately formatted for our purposes, but it
does work on a reasonable number of software packages to be useful.
