build/meson: cleanup of libnm/meson.build

"libnm/fake-typelib/meson.build" modifies the variable "sources",
which is defined by the outer "libnm/meson.build" file.

That is confusing. If a variable is not only used within one "meson.build"
file alone, it should have a unique name. Rename the variable to
"libnm_utils_sources".

Also avoid local variable "deps" which is only used at one place.
