update to SMTPcommands.nse

["DePriest, Jason R." <jrdepriest () gmail com>]

Fixed it to normalize the line endings before replacing them with
commas and I have it remove extra spaces.

I discovered the issue when fingerprinting this mail server
214-2.0.0 This is sendmail version 8.13.1
214-2.0.0 Topics:
214-2.0.0       HELO    EHLO    MAIL    RCPT    DATA
214-2.0.0       RSET    NOOP    QUIT    HELP    VRFY
214-2.0.0       EXPN    VERB    ETRN    DSN     AUTH
214-2.0.0       STARTTLS
214-2.0.0 For more info use "HELP <topic>".
214-2.0.0 To report bugs in the implementation send email to
214-2.0.0       sendmail-bugs () sendmail org.
214-2.0.0 For local information send email to Postmaster at your site.
214 2.0.0 End of HELP info

The output was really ugly[1].  It is still ugly[2], but less so.

I am formulating a way to clean it up more.  I need a generic way to
detect all of the numbers that may appear at the beginning of a line
and figure out what words in all CAPS are commands and which are just
informational.
