Support check-def.sh in meson build

The original check-def.sh called make. In meson, check-def.sh is
replaced by two shell scripts, one for generating cairo.def, the other
for comparing with the library symbols.

The library filename appended to the cairo.def has been omitted as
this is only reqired in autotools builds where the cairo.def is also
to generate cairo.dll in the windows build.

make-cairo-def.sh is based on the cairo.def target in Makefile.am.
meson-check-def.sh is based on check-def.sh
