tools: checkman.sh portability

So, Sami Kerola's checkmans.sh tool caught me stuttering in hwclock.8 and I had to find out why checkmans did not work on my system:

1) Any test file with 'git' or 'lib' in its path fails. Including my entire repo under $PATH/github/util-linux and the ./lib/terminal-colors.d.5 man-page.

2) It depends on the man-db package.

The changes seem to be an improvement as it detected 4 new man-page problems (see separate patch).

I did alter the behavior slightly, previously failed pages required checking them again manually. Now it shows the troff parsing errors in progress. When grog fails there is nothing more to check, and when lexgrog fails I left the old behavior telling the caller to rerun the command, because I did not bother to install man-db to see what lexgrog actually does.

The following changes since commit 2e5bf10e32b00c92a3f7fb8b38d793ea6fc1dff2:

build-sys: add sfdisk.static (2015-01-13 16:59:03 +0100)
