math: Remove the error handling wrapper from hypot and hypotf

The error handling is moved to sysdeps/ieee754 version with no SVID
support.  The compatibility symbol versions still use the wrapper with
SVID error handling around the new code.  There is no new symbol version
nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv).

Only ia64 is unchanged, since it still uses the arch specific
__libm_error_region on its implementation.

Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu.
