vfs: Move dentry-specific functions to a new file

Created a file, vfs_dentry.cc, in the directory ./fs/vfs/ that will
now holds all the dentry-specific functions.

Details:
- Moved lookup_init content to a new function called dentry_init,
and call dentry_init from lookup_init.
- Add declaration for dentry_lookup and dentry_init in fs/vfs/vfs.h

No semantic change has been made here, just refactoring things.
