scripts/nsdeps: make sure to pass all module source files to spatch
The nsdeps script passes a list of the module source files to generate_deps_for_ns() as a space delimited string named $mod_source_files, which then passes it to spatch. But since $mod_source_files is not encased in quotes, each source file in that string is treated as a separate shell function argument (as $2, $3, $4, etc.). However, the spatch invocation only refers to $2, so only the first file out of $mod_source_files is processed by spatch. This causes problems (namely, the MODULE_IMPORT_NS() statement doesn't get inserted) when a module is composed of many source files and the "main" module file containing the MODULE_LICENSE() statement is not the first file listed in $mod_source_files. Fix this by encasing $mod_source_files in quotes so that the entirety of the string is treated as a single argument and can be referred to as $2. In addition, put quotes in the variable assignment of mod_source_files to prevent any shell interpretation and field splitting.
