Fix a problem with reading .module_dep files.

Browse Source 
The source file name that is used as the second argument of a .module_dep file
may be directory qualified (e.g. if we are using source file mapping to
include source files from multiple directories). On Windows, such directory
qualified source file names may use '\' as a path separator. We use the term
parser to read the contents of .module dep files and that requires '\' to be
escaped. However, the code that writes module_dep files does not currently
do the required escaping. Fix that.

compiler/make.module_dep_file.m:
    Escape the source file name before writing it to a .module_dep file.
