Jehan 946a362d9b Revert "libgimpbase: #pragma once"
This reverts commit 06cd254954.

GObject Introspection tools somehow fail to introspect some macros in a
very bizarre way. See issue #14668.

I thought #pragma once was somewhat standard, but it turns out it's not.
And Wikipedia even stays about this:

> While #pragma once is available in most modern compilers, its
> implementation is tricky and might not always be reliable.

Anyway clearly it's not reliable at least regarding GIR tools. I believe
we should hold up on using #pragma once at the very least within our
libgimp* libraries. It is probably fine for app/ or plug-ins/ where we
don't need to introspect anything (and so far we haven't had any
compilation mishap because of this preprocessing directive).
