nommu: fix SYSV SHM for NOMMU
Commit c4caa778157dbbf04116f0ac2111e389b5cd7a29 ("file
->get_unmapped_area() shouldn't duplicate work of get_unmapped_area()")
broke SYSV SHM for NOMMU by taking away the pointer to
shm_get_unmapped_area() from shm_file_operations.
Put it back conditionally on CONFIG_MMU=n.
file->f_ops->get_unmapped_area() is used to find out the base address for a
mapping of a mappable chardev device or mappable memory-based file (such as a
ramfs file). It needs to be called prior to file->f_ops->mmap() being called.
