Fixes a regression on OS X introduced by f83af95.
Don't use --tmpdir for mktemp, because that flag doesn't exist on OS X.
However, using -t is deprecated in GNU coreutils, so as suggested by
@ip1981 we're now using parameter expansion on ${TMPDIR:-/tmp} to
provide /tmp as a fallback if TMPDIR is not set and use it instead.
Also use this approach for nix-prefetch-cvs now in order to stay
consistent.

Instead of relying on $$ to not collide with an existing path.
Quoting the Bash manual about $$:
> Expands to the process ID of the shell. In a () subshell, it expands
> to the process ID of the current shell, not the subshell.
So, this is different from $BASHPID:
> Expands to the process ID of the current bash process. This differs
> from $$ under certain circumstances, such as subshells that do not
> require bash to be re-initialized.
But even $BASHPID is prone to race conditions if the process IDs wrap
around, so to be on the safe side, we're using mktemp here.
Closes#3784.

There are some SVN repositories out there which don't have revision information
tied to externals. By using ignoreExternals, fetchsvn won't fetch these
externals anymore, so the fetch won't fail with a checksum mismatch, should
there be some changes in some of those external repositories.

the server is being spoofed --- only the cryptographic hash of the
output matters.

the tree being fetched from a Subversion repository. The revision
number is now optional (and defaults to HEAD).
This makes `fetchsvn' more pure. First, a URL/revision tuple does
not uniquely identify a file resource, since the repository itself
might change. Second, `svn:external' attributes can cause arbitrary
resources to be exported.
A script `nix-prefetch-svn' has been provided to determine the hash
of a URL.

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.
