[PATCH] debianize: Fix unexpected characters in package lists

[PATCH] debianize: Fix unexpected characters in package lists

[Anton Mikanovich]

Newer dpkg-deb versions got more pedantic to the control file format.

Introduce debian package list format helper to cleanup empty items or
unexpected commas in dependency options passing to the default control
file.

This prevents errors like:
| dpkg-deb: error: unexpected end of file in archive magic version number in *.deb
| Unexpected character ')' parsing formula 'Package (= ), Architecture (= ), $PackageType (= deb)'!
| There have been errors!
caused by empty DEBIAN_BUILD_DEPENDS value in the line:
| Build-Depends: debhelper-compat (= ${DEBIAN_COMPAT}), ${DEBIAN_BUILD_DEPENDS}
which results in:
| Build-Depends: debhelper-compat (= 13),
