Motivation and Context

Fixes a compilation error:

error: SwiftCompile normal arm64 .../Sources/ContainerBuild/Builder.swift failed with a nonzero exit code. Command line:     cd ...
    builtin-SwiftPerFileCompile Builder.swift
.../Sources/ContainerBuild/Builder.swift:111:13: error: unstructured throwing task created by 'init(name:priority:operation:)' is not used, which may accidentally ignore errors thrown inside the task [#NoUseUnstructuredThrowingTask]
109 | 
110 |         if let terminal = config.terminal {
111 |             Task {
    |             |- error: unstructured throwing task created by 'init(name:priority:operation:)' is not used, which may accidentally ignore errors thrown inside the task [#NoUseUnstructuredThrowingTask]
    |             `- note: to silence this warning, handle the error inside the task, or store/discard the task value explicitly
112 |                 let winchHandler = AsyncSignalHandler.create(notify: [SIGWINCH])
113 |                 let setWinch = { (rows: UInt16, cols: UInt16) in

Also, fixes compilation warnings:

.../Sources/Plugins/RuntimeLinux/RuntimeLinuxHelper+Start.swift:46:13: warning: cannot use struct 'FilePath' in a property declaration member of a type not marked '@_implementationOnly'; 'SystemPackage' was not imported by this file

    |             `- warning: cannot use struct 'FilePath' in a property declaration member of a type not marked '@_implementationOnly'; 'SystemPackage' was not imported by this file

    |             `- warning: cannot use struct 'FilePath' in a property declaration member of a type not marked '@_implementationOnly'; 'SystemPackage' was not imported by this file
