Subject: [PATCH] ci: Set CCACHE_SLOPPINESS as required for using PCH

While the solution of setting CCACHE_SLOPPINESS in the makefiles seems
to work locally, the CI has been reporting high miss rates since the
PCH patch landed. Possibly the CI environment has CCACHE_SLOPPINESS set
to the empty string, which prevents Make ?= to apply.
