[BH-628] Cleaned up module-vfs cmake

Cleaned up pattern of sharing source files among libraries
using cached lists, ultimately leading to silent linkage
failures. Symbols build repeatedly in different libraries
was linked depending on which library was passed in linker
command arguments first, so for example in same cases
cellular bsp files compiled in module-vfs was linked instead
of those from module-bsp leading to failure of cellular work
despite no explicite build failure.
