fs/ramfs/file-nommu.c: make ramfs_nommu_get_unmapped_area() and ramfs_nommu_mmap() static

Browse Source 
Since commit 853ac43ab1 ("shmem: unify regular and tiny shmem"),
ramfs_nommu_get_unmapped_area() and ramfs_nommu_mmap() are not directly
referenced outside of file-nommu.c.  Thus make them static.
