configure: fix performance regression due to PIC objects
Because most files in QEMU are grouped into static libraries, Meson conservatively
compiles them with -fPIC. This is overkill and produces slowdowns up to 20% on
some TCG tests.
As a stopgap measure, use the b_staticpic option to limit the slowdown to
--enable-pie. https://github.com/mesonbuild/meson/pull/7760 will allow
us to use b_staticpic=false and let Meson do the right thing.
