cairo 1.10.2: enable tee backend

This is needed for firefox:

| checking CAIRO_LIBS... -lcairo -lpixman-1 -lfreetype -lfontconfig
| checking for cairo-tee >= 1.10... Package cairo-tee was not found in the pkg-config search path. Perhaps you should add the directory containing `cairo-tee.pc' to the PKG_CONFIG_PATH environment variable No package 'cairo-tee' found
| configure: error: Library requirements (cairo-tee >= 1.10) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
