fca1b82417 fusefrontend: relay Utimens to go-fuse 
Commit af5441dcd9 has caused a
regression ( https://github.com/rfjakob/gocryptfs/issues/35 )
that is fixed by this commit.

The go-fuse library by now has all the syscall wrappers in
place to correctly handle Utimens, also for symlinks.

Instead of duplicating the effort here just call into go-fuse.

Closes #35

8f1e51789d tests: set the times on a symlink

Also remove the spurious sleep in the test.

af5441dcd9 fusefrontend: use NsecToTimespec() for Utimens 
This fixes a build problem on 32-bit hosts:

  internal/fusefrontend/file.go:400: cannot use a.Unix() (type int64) as
  type int32 in assignment
  internal/fusefrontend/file.go:406: cannot use m.Unix() (type int64) as
  type int32 in assignment

It also enables full nanosecond timestamps for dates
after 1970.

02aab5d21f Drop obsolete .drone.yml

instance that supports FUSE, but for now it provides no advantages
to Travis CI.

1c54fcd04b tests: use unmount wrapper in ResetTmpDir 
This should make it work on OSX.

Also, split unmount into two functions. Depending on what you
want,

* UnmountErr returns the resulting error
* UnmountPanic panics if the error was not nil

it is int32 and that caused a compile failure.
