build: Fix PATH shell export

When $(wildcard /usr/lib*/ccache) returns more than one directory, they
are separated by space and it ends up setting only first one to PATH
variable while the rest of the string is just throwed to bash and it
ends up breaking the build.  This change replaces space by colon to keep
desired PATH string syntax.
