fix(build): remove -rdynamic from compiler flags (#506)

The -rdynamic flag was incorrectly added to CEF_COMPILER_FLAGS, causing
clang to fail with 'argument unused during compilation' when -Werror is
enabled. This flag is only valid during linking.

Remove -rdynamic from CEF_COMPILER_FLAGS while keeping it in
CEF_EXE_LINKER_FLAGS where it belongs.

Fixes #501
