configure.sh: expanding deps() to create sys/pxe/isolinux configs

Expanding deps() function to create the distro specific syslinux
configurations with a separate config for each of the following:

   isolinux (bios) - var/config/isolinux.inc
   pxelinux (bios) - var/config/pxelinux.inc
   syslinux (bios) - var/config/syslinux.inc
   BOOTX64.EFI (uefi) - var/config/syslx64.inc
   syslinux.efi (uefi) - var/config/pxelx64.inc

I do not have an IA32 UEFI system with which to test IA32 boot configurations,
so I am leaving off specific IA32 configuration files for now.
