[check] Replace compiled symbol visibility checker with shell script.
Behdad Esfahbod objected to the execution of a compiled program to check
symbol visibility as it makes cross-compilation more difficult.
Instead of executing the program, this method conditionally exports
a variable if cairo uses symbol hiding and scans the executable for
that symbol in a similar manner to check-def.sh. This has the slight
advantage of using the Makefile for performing the compilation, rather
than attempting to invoke $(CPP) from a shell script within the test
environment.
