tool/depot: fix forwarding of CCACHE

Browse Source 
The depot tool 'build_bin_archive' used to ask only whether CCACHE is empty or
not and, if it wasn't empty, the tool added 'CCACHE := yes' to the build.conf
of the temporary build dir. This caused the sub-build processes to use ccache
even when the top-level CCACHE variable was set to a bogus value.

Also adds documentation of the CCACHE variable to the help message of the
'build' and 'build_bin_archive' tool.
