[Buildroot] [git commit branch/next] fs/iso9660: use 'depends on' instead of 'select' for bootloader

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=bd256e96c07c31b3804e079dd498fe4a4012b64e
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

In preparation to the introduction of the support for other
bootloaders than Grub, this commit switches from having the iso9660
support "select" the necessary bootloader to using a "depends on".

The main motivation is that the isolinux bootloader support will
really need to do a "depends on", due to the need of having a certain
option enabled, but this option being a kconfig "choice".
