-												curl: remove MANUAL from -M output

... and remove it from the dist tarball. It has served its time, it
barely gets updated anymore and "everything curl" is now convering all
this document once tried to include, and does it more and better.

In the compressed scenario, this removes ~15K data from the binary,
which is 25% of the -M output.

It remains in the git repo for now for as long as the web site builds a
page using that as source. It renders poorly on the site (especially for
mobile users) so its not even good there.

Closes #3587

-												mkhelp: Remove trailing carriage return from every line of input

- Get rid of this flood of warnings in Windows mingw build:
warning: missing terminating " character

The warning is due to the carriage return. When msysgit checks out files
from the repo by default it converts the line endings to CRLF. Prior to
this change when mkhelp.pl processed the MANUAL and curl.1 in CRLF
format the trailing carriage returns caused unnecessary CR in the
output.
