syslinux PXE: Forced all TFTP paths to be absolute

Browse source 
By default, syslinux interprets TFTP paths as relative to the location of the *.c32 modules, regardless whether a path starts with a slash. Without the `::` that I added to all of these paths, syslinux cannot find these files. It searches for them in /%INSTALL_DIR%/syslinux//%INSTALL_DIR%/boot/x86_64/vmlinuz-linux, etc.

-------
- Fix the PXE support. PXELINUX was having trouble finding the kernel and initrds. Now, archiso forces syslinux to
interpret all TFTP paths as absolute. That seems to have solved the issue.
