playTests.sh didn't work when `ZSTD_BIN` or `DATAGEN_BIN` had a space in
the path name. This happens for me because I split the cmake build
directory by compiler name, like "Clang 9.0.0".
The fix is to replace all instances of `$ZSTD` with the `zstd()`
function, and the replace `$DATAGEN` with `datagen()`. This will allow
us to change how we call zstd/datagen in the future without having to
change every callsite.

/dev/null permissions were modified when using sudo rights.
This fixes this bug during decompression.
More importantly, this patch adds a test, triggered in TravisCI,
ensuring unaltered /dev/null permissions.
date(1) is used to display the last modification time of a file, which
is not supported on OpenBSD, FreeBSD and Darwin. Instead use stat(1).
Tested on OpenBSD.
