Fix reading of XDG style semicolon separated lists with escaped ';'

Previously the warning "Invalid escape sequence "\;"." would appear and
"\;" was replaced with just the backslash as is done for all
unrecognized escape sequences. Keep both characters so that
readXdgListEntry() works with values containing semicolons
