[libc++] Fix negate and bit_xor in C++03 frozen headers (#187573)

Browse Source 
An unintended change in #134045 gave them a default template argument,
which is supposed to be from C++14 onwards.

I considered adding a test for this but it is really awkward to test
that we don't support passing no template argument in C++03 mode and
that provides little value, so I decided against it.
