[yocto] [meta-raspberrypi][PATCH] linux-raspberrypi: Adjust for libexecdir changes

[Khem Raj]

libexecdir has changed its location in latest OE core, it used to be
pointing to /usr/lib which was essentially same as libdir and when
hardcoded in do_rpiboot_mkimage it worked.

Fixes kernel build failures e.g.

DEBUG: Executing shell function do_rpiboot_mkimage

line 111:
