cygport: calm can fail when BUILD_REQUIRES contains some newlines

[Lemures Lemniscati]

Hi!

It may cause an issue when BUILD_REQUIRES contains some newlines in
a cygport file. 

Because cygport-0.34-1 generates *src.hint with raw BUILD_REQUIRES, and
extra newlines in 'build-depends' may be rejected by calm when uploading
packages.


This is a work-around patch by squeezing white spaces in BUILD_REQUIRES.
