MIPS/testsuite: Fix bseli.b fail in msa-builtins.c
commit 05daf617ea22e1d818295ed2d037456937e23530

[committed] [v2] More logical op simplifications in simplify-rtx.cc
does some simplifications, and then `bseli.b $w1,$w0,255` is found that
it is same with `or.v $w1,$w0,$w1`. So there will be no bseli.b instruction
generated.
Let's use 254 instead of 255 to test the generation of `bseli.b`.
gcc/testsuite
* gcc.target/mips/msa-builtins.c: Use 254 instead of 255 for
bseli.b, as `bseli.b $w0,$w1,255` is same as `or.v $w0,$w0,$w1`.
