[Automake] Pass --no-demangle to the linker by default to get the mangled symbols

* GNUmakefile.am: Pass the --no-demangle option to the linker by default. This is done by appending
the flag to the LDFLAGS variable. While the AM_LDFLAGS variable would be more appropriate, it's not
at all used when linking installable libraries like libwebkitgtk and libwebkit2gtk, so the LDFLAGS
variable is used instead.
