[SFrame-V3] sframe: gas: libsframe: remove padding field from FDE

Remove the unused sfde_func_padding2 member from the
sframe_func_desc_entry_v3 structure.

A later patch in this series reorganizes the members of the FDE
structure in a way explicit padding is no longer necessary to keep
natural alignment.  So remove the explicit padding now.
