syslinux.bbclass: Enable additional kernel parameters for syslinux

Browse Source 
Add additional parameter 'SYSLINUX_KERNEL_ARGS' in order to allow
for specific kernel parameters to be set when using syslinux.

The extra kernel parameters are added to btype[1] and then written out
as part of the APPEND field.

(From OE-Core rev: d78c4d51ed266c14b0425f6abf553392c6ebe408)
