[build-presets] Add post-packaging testing to Linux.
[build-presets] Add post-packaging testing to Linux.

Adds the test-installable-package=1 argument to build-script-impl for
packages created for Linux. This runs a series of automated tests and
sanity checks on the package as a whole, testing lldb, swiftc, swiftpm,
and the repl, amongst other things.
