[ELF] Fix a null pointer dereference when --emit-relocs and --strip-debug are used together
Fixes https://bugs.llvm.org//show_bug.cgi?id=44878
When --strip-debug is specified, .debug* are removed from inputSections
while .rel[a].debug* (incorrectly) remain.
LinkerScript::addOrphanSections() requires the output section of a relocated
InputSectionBase to be created first.
.debug* are not in inputSections ->
output sections .debug* are not created ->
getOutputSectionName(.rel[a].debug*) dereferences a null pointer.
Fix the null pointer dereference by deleting .rel[a].debug* from inputSections as well.
