Install MCS camera drivers more cleanly.

The canonexp and shutter programs in ics_mcsActor/source/canonexp are currently installed to:

INSTALLPATH = /usr/local/bin
CONFIGPATH = /home/pfs/mhs/devel/ics_mcsActor/etc

They could copy into (and be used from) $(PRODUCT_DIR)/bin and $(PRODUCT_DIR)/etc. Something like:

INSTALLPATH = ../../bin
CONFIGPATH = ../../etc

Given that they have to built against external libraries, and that the shutter requires building a kernel driver, I suspect that the whole source directory should actually be pulled out into its own ics_mcs_devices product.
