osdep.h: Drop no-longer-needed Coverity workarounds

In commit a1a98357e3fd in 2018 we added some workarounds for Coverity
not being able to handle the _Float* types introduced by recent
glibc.  Newer versions of the Coverity scan tools have support for
these types, and will fail with errors about duplicate typedefs if we
have our workaround.  Remove our copy of the typedefs.
