Filecount: directory permission denied blocks input regardless of recurse parameter

[jnguiot]

Relevant telegraf.conf:

[[inputs.filecount]]
directory = "/tmp/foo/"
name = "aaa"
recursive = false

System info:

Telegraf 1.9.4 (git: HEAD 4da8d0a)
Ubuntu 16.04

Steps to reproduce:

1. create this architecture in /tmp:

foo
|-- [-rw-rw-r--] aaa
`-- [d---------] bar

foo and bar are directories
aaa is a regular file
bar cannot be read by telegraf user (here, it is simulated by a 000 chmod)
2. Create the file /tmp/aaa.conf with this content:

[[inputs.filecount]]
directory = "/tmp/foo/"
name = "aaa"
recursive = false

3. execute config file: telegraf --config /tmp/aaa.conf --test

Expected behavior:

Telegraf process should return:
> filecount,directory=/tmp/foo/,host=computer count=1i 1550582182000000000

Actual behavior:

Telegraf process returns:
2019-02-19T13:17:01Z E! [inputs.filecount]: Error in plugin: open /tmp/foo/bar: permission denied

Additional info:

Since recurse is set to false, telegraf should not care about subdirectories, especially, it should not go into error.
I am still looking for a workaround.

A workaround is to use the nightly as this has been resolved for 1.10

Ok. Thank you for the quick bugfix!
