quiet test in fread/download.file

[jangorecki]

When running test.data.table() I get:

...
Running test id 1378.2     trying URL 'file:///usr/local/lib/R/site-library/data.table/tests/russellCRLF.csv'
Content type 'unknown' length 1210 bytes
==================================================
downloaded 1210 bytes

Running test id 1378.3     trying URL 'file:///usr/local/lib/R/site-library/data.table/tests/russellCRCRLF.csv'
Content type 'unknown' length 1248 bytes
==================================================
downloaded 1248 bytes
...

Environment which I'm using is official docker r-base image. It has download.file.method preconfigured as:

... && echo 'options(repos = c(CRAN = "https://cran.rstudio.com/"), download.file.method = "libcurl")' >> /etc/R/Rprofile.site \
...

And the sessionInfo() is:

R version 3.2.2 (2015-08-14)

attached base packages:

other attached packages:
[1] nlme_3.1-122     data.table_1.9.6

loaded via a namespace (and not attached):
[1] tools_3.2.2     grid_3.2.2      chron_2.3-47    lattice_0.20-33

Should be straight to fix.
