    doc.docbook.mk: Fix LATESTREVISION determination, causes build failure on non-English locales
    
    Fixes, e.g., manual articles/books build (i.e., typing `make` in the right
    directory).
    
    There were two problems:
    1. Git or SVN information retrieval depends on the current locale, and doesn't
    work with non-English ones.
    2. Fallback for LATESTREVISION most of the time (sometimes works, probable
    race) itself fails because PWD is set to document's directory + '/obj', but
    sources are in the document's directory.
    
    Problem 2 is the most annoying because documentation builds simply fails
    (`xsltproc` becomes unable to resolve 'latestrevision.*' variables in, e.g.,
    articles). But point 2's failure appears only because of point 1's failure,
    which doesn't happen on a machine with English or C locale.
