6aa64627c8 Support user namespaces being disabled 
If max_user_namespaces is set to 0, then don't run the build in a user
namespace.

Fixes #4092.

d761485010 Prevent a deadlock when user namespace setup fails 
Observed on Centos 7 when user namespaces are disabled:
DerivationGoal::startBuilder() throws an exception, ~DerivationGoal()
waits for the child process to exit, but the child process hangs
forever in drainFD(userNamespaceSync.readSide.get()) in
DerivationGoal::runChild(). Not sure why the SIGKILL doesn't get
through.

Issue #4092.

Fix max-jobs option 
After 0ed946aa61, max-jobs setting (-j/--max-jobs)
stopped working.

The reason was that nrLocalBuilds (which compared to maxBuildJobs to figure
out whether the limit is reached or not) is not incremented yet when tryBuild
is started; So, the solution is to move the check to tryLocalBuild.

Closes https://github.com/nixos/nix/issues/3763

See comments for security concerns.

Also optimize goal creation by not traversing map twice.

c4bf219b55 Don't link deriver until after any delayed exception is thrown 
Otherwise, we will associate fixed-output derivations with outputs that
they did indeed produce, but which had the wrong hash. That's no good.

aad4abcc9c Fix floating CA tests 
We will sometimes try to query the outputs of derivations we can't
resolve. That's fine; it just means we don't know what those outputs are
yet.
