[patch, nios2] don't set sh_entsize for PLT section

[Sandra Loosemore]

The nios2 BFD port is presently setting the sh_entsize ELF attribute for 
the PLT section to the size of the first PLT entry.  However, this is 
incorrect; the nios2 ABI allows PLT entries of different sizes, and the 
ELF specification says that sh_entsize should be nonzero only if all 
entries are that size.  Since BFD normally defaults this to zero, all 
that's needed is to delete the code that is erroneously setting sh_entsize.

This bug was found by a customer who was doing elfutils/libelf testing, 
but readelf on a simple "hello, world" program was sufficient to show 
the problem and verify the fix.

Patch committed after usual regression testing on nios2-linux-gnu target.
