build/gmodule-2.0.pc: Move compiler flags from Libs to Cflags

Browse Source 
Previously, `-Wl,--export-dynamic` was in `Libs` key of `gmodule-2.0.pc`,
even though `-Wl` is a compiler flag, rather than a linker one.
This caused issues with API reference builds in evolution-data-server,
which passes the output of `pkg-config --libs` through `--ldflags`
argument of `gtkdoc-scan`, which are forwarded unchanged to `ld`:

    ld: unrecognized option '-Wl,--export-dynamic'

Let’s move the flag to `Cflags` so that the compiler can deal with it.
