Does not support FIPS compliance and actually breaks NPM

[ayohrling]

When NodeJS is compiled for FIPS-compliance, write-file-atomic actually breaks NPM.

When NPM attempts to write the local cache file .cache.json using writeFile from the library, it throws the following:

fips_md.c(146): OpenSSL internal error, assertion failed: Digest update previous FIPS forbidden algorithm error ignored
Aborted

Instead of hardcoding md5 hash for the temporary name, consider moving to something higher like sha1 at a minimum or check for FIPs compliance and make it variable. I tested by moving the function createhash() call to sha1 and it proceeds fine.

@ayohrling Should be resolved in #7.

This is fixed by 22dd875, which was landed in lieu of #7 because of my poor reading comprehension skills (sorry again, @stefanmb). [email protected] (currently npm@next) includes the fixed version of write-file-atomic, and should work with FIPS builds of Node.js. Thanks for the heads up!
