[PULL 47/68] meson: use prefer_static option

[Paolo Bonzini <pbonzini@redhat.com>]

The option is new in Meson 0.63 and removes the need to pass "static:
true" to all dependency and find_library invocation.  Actually cleaning
up the invocations is left for a separate patch.

 This avoids warnings on static builds of user-mode emulators, for example.
