Fixes #8681.

Add boot loader packagefs support

* Add pread().
* Add Node::ReadLink() to read a symbolic link path.
* Add Directory::LookupDontTraverse() and make Lookup() non-abstract.
Lookup() is implemented via LookupDontTraverse() and Node::ReadLink().
* Adjust all FS implementations accordingly.
* Add a packagefs implementation. Unlike other FS implementations it
isn't a pseudo-module, but provides a function to explicitly mount a
package file (packagefs_mount_file()).
* Finish BootVolume::SetTo() implementation, mounting the package file
and replacing fSystemDirectory.

Now the boot loader can load the kernel and boot modules from a packaged
system. The kernel boots up to the point where the boot volume is
mounted.

Renamed src/kernel to src/system.
