[OE-core] [PATCH] syslinux.bbclass: ensure creation of output directory

[Ed Bartosh]

build_syslinux_cfg function creates syslinux configuration file.
The code assumes that the output directory exists, which is not
always the case. For example rm_work task removes rootfs directory
structure and causes build_syslinux_cfg to fail with this error:
Unable to open ../<image>-<version>/syslinux_vm.cfg

Made build_syslinux_cfg depend on output directory to ensure that
directory is created before running the function.
