[opus] [Aarch64 v2 15/18] Clean up formatting of configure output for ARM intrinsics detection.

[Jonathan Lennox]

This makes it match the formatting of the output for ARM assembly
better, and removes some redundant repetition of the word
"intrinsics".  It also fixes the output if a compiler supports RTCD
for Neon intrinsics but not assembly.
