Subject: all: speed up tests

Mark tests as parallel where makes sense.
Speed up sys.TransitivelyEnabledCalls.

Execution time is now:

ok  	github.com/google/syzkaller/config		0.172s
ok  	github.com/google/syzkaller/cover		0.060s
ok  	github.com/google/syzkaller/csource		3.081s

ok  	github.com/google/syzkaller/syz-hub/state	0.427s
ok  	github.com/google/syzkaller/vm			0.052s

However, main time is still taken by rebuilding sys package.

Fixes #182
