[OE-core] [PATCH] toolchain-scripts: remove CCACHE_PATH from environment script

[Joshua Lock]

CCACHE_PATH was added to the toolchain-scripts in commit
1d31ddb856a80ba9da1a64ed5d701dc0f7351ef7 without a detailed
explanation as to why. This commit removes that environment
variable as it's causing failures since the introduction of
host_gcc_version() to oe.utils in
d36f41e5658bbbb6080ee833027879c119edf3e0, as used by
uninative to determine NATIVELSBSTRING.

This causes errors when the host has ccache available in in PATH
- host_gcc_version() fails because ccache has been told to only
look for the compiler in CCACHE_PATH and can't find gcc in order
to check its version. Toolchain compilers aren't detected due to
the binaries being prefixed with the triplet of the target.
