[syslinux] pxelinux doesn't suppress common prefix if nothing precedes double colon

Contrary to the pxelinux.doc documentation, the common filename prefix
is only suppressed if an explicit hostname or IP address precedes the
double colon, e.g. 192.168.1.1::/foobar. A tcpdump of TFTP requests
reveals that the double colon does nothing in implicit case (::/foobar
is the same as /foobar, i.e. gets mapped to /pxelinux//foobar or
whatever). 0.0.0.0::/foobar also does this.
I first noticed the problem in 3.51, and have confirmed that it still
exists in the current (3.52 0x46d0cdef) git code.
Sorry, my 80x86 assembly skills are too rusty to fix this myself, but it
should be 100% reproduceable.
