package/nodejs: use --with-arm-fpu option on ARM

nodejs can use some FPU instructions on ARM, but it needs to know that
thanks to the --with-arm-fpu option. Without this, it may use the
wrong FPU setting, such as use VFPv3 even if only a VFPv3-D16 is
available. This has been reported as bug #12166, where the compiled
node binary had some floating point instructions using floating point
registers above 16 on a VFPv3-D16 system.

This commit makes sure we pass the appropriate --with-arm-fpu value
when it makes sense. Note that NodeJS only has explicit support for a
subset of the FPUs, for the ones that are not explicitly supported, we
simply pass no --with-arm-fpu value.
