[ELF][NFC] Allow non-GotSection for addAddendOnlyRelocIfNonPreemptible (

llvm#104228)

This was done as an afterthought in c3c9e45 without justification.
Nothing relies on it being a specific kind of section, and downstream in
CHERI LLVM we pass a non-GotSection to this function. Thus revert this
overly-restrictive change and allow downstreams to pass other section
types again.

This partially reverts commit c3c9e45.
