[OE-core] [PATCH 1/4] base.bbclass: Remove invalid ccache related code

[Robert Yang]

The code is in setup_hosttools_dir(), it searches ccache in PATH in reverse
order, I can't figure out what it is used for, maybe it is aimed to use host's
ccache rather than recipe-sysroot-native/usr/bin/ccache, but the later one
isn't in original PATH, so remove the code.
