[PATCH 01/11] build: do not include @block.syms/@qemu.sys with modules disabled

[Paolo Bonzini <pbonzini@redhat.com>]

Including specific symbols used by modules is not necessary for
monolithic executables.  This avoids a failure where emcc does not
support @file syntax inside a response file---which in turn breaks
the WebAssembly build if the command line is long enough that meson
decides to use a response file.
