[ELF] - Do not merge sections from SHT_GROUP when -relocatable

This is PR34506.

Imagine we have 2 sections the same name but different COMDAT groups:

.section        .foo,"axG",@progbits,bar,comdat
.section        .foo,"axG",@progbits,zed,comdat
When linking relocatable we do not merge SHT_GROUP sections. But still would merge
both input sections .foo into single output section .foo.
As a result we will have 2 different SHT_GROUPs containing the same section, what
is wrong.

Patch fixes the issue, preventing merging SHF_GROUP sections with any others.
