[PATCH 2/2] devtools: use libabigail rule for mlx glue drivers

[David Marchand <david.marchand@redhat.com>]

Convert the existing exception in the ABI script into a libabigail
suppression rule.

Note: file_name_regexp could be used to achive the same with versions of
libabigail < 1.7 but soname_regexp has been preferred here since it is
already used with a recent change on common/mlx5.

While at it, fix indent from a recent change.
