linux-user: arm: handle CPSR.E correctly in strex emulation
Now that CPSR.E is set correctly, prepare for when setend will be able
to change it; bswap data in and out of strex manually by comparing
SCTLR.B, CPSR.E and TARGET_WORDS_BIGENDIAN (we do not have the luxury
of using TCGMemOps).

[ PC changes:
* Moved SCTLR/CPSR logic to arm_cpu_data_is_big_endian
]
