We recently moved glib detection code to meson but this changes the
linker command line from -lglib-2.0 to using a path to libglib-2.0.so.
This does not work for static linking, which is used by stress.c:

 $ make V=1 tests/migration/initrd-stress.img
 cc -m64 -mcx16 -o tests/migration/stress ... -static -Wl,--start-group
 /usr/lib64/libglib-2.0.so -Wl,--end-group
 ...
 bin/ld: attempted static link of dynamic object `/usr/lib64/libglib-2.0.so'

Add a specific dependency for stress.c, which is linked statically.
The compiler command line is now:

 cc -m64 -mcx16 -o tests/migration/stress ... -static -pthread
 -Wl,--start-group -lm /usr/lib64/libpcre.a -lglib-2.0 -Wl,--end-group
