[RS6000] Simplify setting of fixed_regs[RS6000_PIC_OFFSET_TABLE_REGNUM]
This makes the conditions look the same as other places that deal with
RS6000_PIC_OFFSET_TABLE_REGNUM, eg. first_reg_to_save. No functional
changes.
* config/rs6000/rs6000.c (rs6000_conditional_register_usage):
Remove redundant PIC_OFFSET_TABLE_REGNUM test. Replace with
flag_pic test for Darwin.
