jewel: remove non-CM/CWM configurations

TWRP is a separate project. Really, we need to abide by the "eat your own
dogfood" philosophy anyways and use CWM to motivate improving it.

Note: although TARGET_RECOVERY_PIXEL_FORMAT is not TWRP specific, it is
already defined in s4-common.

jewel: use block device paths in recovery fstab

This re-enables CWM's advanced partition functions to create /sd-ext on
external storage. It also squelches some error messages that show up on
Koush's special touch version of CWM.
