CCACHE_BUILD: Only export CCACHE_PATH= if it was already set with a value.

Older ccache don't work with an empty CCACHE_PATH value.  They will error with:
  ccache: FATAL: Could not find compiler "cc" in PATH
  make: "/mnt/bdrewery/git/onefs/src/share/mk/bsd.compiler.mk" line 134: Unable to determine compiler type for /usr/local/bin/ccache cc.  Consider setting COMPILER_TYPE.
