Use the library SONAME as the module name when present

[gabrielesvelto]

ELF files can have a SONAME that differs from the filename, when they do the SONAME should be used as the module name in the first line of output, like:

MODULE Linux x86_64 B29B5D0942181476F8BE6AD24FF571C80 libgallium_drv_video.so

Instead of

MODULE Linux x86_64 B29B5D0942181476F8BE6AD24FF571C80 nouveau_drv_video.so

For a filename called nouveau_drv_video.so in mesa, for example.

I made a PR in symbolic to add the possibility to get soname (for elf) and dylib name (for macho):
getsentry/symbolic#252

This was fixed, I forgot to close it.
