[OE-core] [PATCH] sdl2: fix sdl2.pc include paths

[Andreas Müller]

My two comments:

1. There is already an upgrade libsdl2 -> 2.09 pending so this patch
needs rebase [1]
2. Removing CFLAGS is easier but potentially a risk of unwanted
effects. My sdl2.pc contains -D_REENTRANT. This should be obsolete but
who guarantees that there isn't some old application still requiring
it (because it is set in other build environments).
