[meta-xilinx] local.conf.sample doesn't need to set parallelism

[Robert P. J. Day]

  just noticed that local.conf.sample in meta-xilinx layer explicitly
sets

BB_NUMBER_THREADS = "8"
PARALLEL_MAKE = "-j 8"

that's probably unnecessary as OE's bitbake.conf calculates the proper
values for these values:

# Default to setting automatically based on cpu count
BB_NUMBER_THREADS ?= "${@oe.utils.cpu_count()}"

# Default to setting automatically based on cpu count
PARALLEL_MAKE ?= "-j ${@oe.utils.cpu_count()}"
