fix: processor architecture selector for Linux

[smihica]

📜 Description

The processor architecture in the relevant section was as follows,

switch (SysInfo.kernelArchitecture.name.toLowerCase()) {
  case 'arm':
  case 'armv6':
  case 'armv7':
    return HostPlatform.linuxArmv7;
  case 'aarch64':
    return HostPlatform.linuxAarch64;
  case 'amd64':
  case 'x86_64':
    return HostPlatform.linux64bit;

but the SysInfo.kernelArchitecture.name returns different values.
See here => https://github.com/onepub-dev/system_info/blob/master/lib/src/processor_architecture.dart

My aarch64 linux was failing to run by this bug.

$ dart run sentry_dart_plugin
[❚❚❚❚❚❚❚❚❚❚❚❚❚❚❚❚❚❚❚❚❚❚] 0% reading config values..        
Searching for pubspec.yaml or sentry.properties config...
Found config from pubspec.yaml
Failed to download Sentry CLI: Exception: Host platform not supported: linux ARM64

↑ The name was ARM64

This fixes the problem.
