xtensa: adjust expected output in ld TLS tests

objdump output for l32r opcode was changed in commit b3ea7639
("opcodes: xtensa: display loaded literal value"), but xtensa linker TLS
relaxation tests weren't adjusted accordingly.
readelf output was changed in commit 23356397 ("Adjust readelf's
output so that section symbols without a name as shown with their
section name."), but xtensa linker TLS relaxation tests weren't adjusted
accordingly.
Fix expected output changes in xtensa ld TLS relaxation tests.
