Configure,test/recipes: "pin" glob to File::Glob::glob.

As it turns out default glob's behaviour for quoted argument varies
from version to version, making it impossible to Configure or run
tests in some cases. The reason for quoting globs was to accommodate
source path with spaces in its name, which was treated by default glob
as multiple paths. File::Glob::glob on the other hand doesn't consider
spaces as delimiters and therefore works with unquoted patterns.

[Unfortunaltely File::Glob::glob, being too csh-ly, doesn't work
on VMS, hence the "pinning" is conditional.]
