On some systems, the link is of the form "[device]:inode", which
can be used to open the executable, but is useless if you want
the path to it. Thus we check that the path is an actual absolute
path. (Using '/' here is safe; it isn't the path separator
everywhere, but it is on all systems that have PROCFS_EXE_LINK.)
