support platforms which does not have shasum command

[cou929]

Use sha1sum command if there is no shasum command.

Such like CentOS, for example, there are platforms which doesn't have 'shasum' command. On the such platform, we can install nothing because cannot calculate checksum. Like below:

    $ nvm install v0.9.1
    ######################################################################## 100.0%
    nvm:1: command not found: shasum
    Checksums do not match.
    Binary download failed, trying source.
    Additional options while compiling:
    ######################################################################## 100.0%
    nvm:1: command not found: shasum
    Checksums do not match.
    nvm: install v0.9.1 failed!

I realize this issue is closed, but I just grabbed master on OSX and cannot install any remote versions of node. I'm receiving basically the same output:

RadioFreePro:bin drew$ nvm install v0.8.15
######################################################################## 100.0%
bash: sha1sum: command not found
Checksums do not match.
Binary download failed, trying source.
Additional options while compiling: 
######################################################################## 100.0%
bash: sha1sum: command not found
Checksums do not match.
nvm: install v0.8.15 failed!

My knowledge of bash is limited, but doesn't directing which shasum to /dev/null defeat the purpose of the if?

If I change it to be similar to the curl check:

if [ ! `which shasum` ]; then
  shasum='sha1sum'
fi

then I'm able to install again. If this sounds alright, I can make a pull request.

I think kirbysayshi's change is right. The condition if [ !which shasum 2> /dev/null]; of my patch will be always true. I'm sorry for my wrong code.

Same issue for Centos 6.4:

$ which shasum
/usr/bin/which: no shasum in (/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/rngadam/bin)
$ which sha1sum
/usr/bin/sha1sum

@kirbysayshi master currently has if [ -z "\which curl" ] - if your change would work better, please do make a pull request.

For OSX user:

just add alias sha1sum='shashum' to your ~/.profile

This should also work on linux but with the file ~/.bashrc
