RFR: 8350499: Minimal build fails with slowdebug builds

[Ao Qi]

minimal build fails with slowdebug builds after [8311208](https://github.com/openjdk/jdk/commit/498a58244d79) (permissions required):


Building target 'images' in configuration 'linux-x86_64-minimal-slowdebug'
/usr/bin/ld: /home/aoqi/work/theaoqi/jdk/build/linux-x86_64-minimal-slowdebug/hotspot/variant-minimal/libjvm/objs/verifier.o: in function `Verifier::verify(InstanceKlass*, bool, JavaThread*)':

ERROR: Build failed for target 'images' in configuration 'linux-x86_64-minimal-slowdebug' (exit code 2) 


It may be because the systemDictionaryShared.cpp file is [excluded](https://github.com/openjdk/jdk/blob/bd8ad309b59bceb3073a8d6411cca74e73508885/make/hotspot/lib/JvmFeatures.gmk#L130) when using slowdebug and minimal builds.
