[llvm] [DWARF] Clarify a variable name. NFC (PR #88814)

[Fangrui Song via llvm-commits]

https://github.com/MaskRay created https://github.com/llvm/llvm-project/pull/88814

The parameter of `findDebugNamesOffsets` has been renamed to
`EndOfHeaderOffset` in #88064 to make it clear it is a section offset
instead of an offset relative to the current name index. Rename the call
site variable as well.
