[libvirt] [PATCH] build: exclude more files from all the syntax checks

[Pino Toscano]

The majority of the syntax check is taylored for C sources, so some of
the checks already cause false positives for non-C sources (and thus
there are exclusion regexps in place).

Instead, just exclude more non-C files from all the checks:
- pot files: they are templates for po files (already excluded), and
  they are automatically generated from sources
- pl files: Perl sources, which have own APIs, style, etc; they are
  helper scripts, not "real" sources
- spec/spec.in files: RPM packaging files
- js/woff/html.in files: files for web pages
- diff/patch files: patches
- stp files: SystemTap scripts
- syms files: linker symbols files
- conf files: generic configuration files
- data/cpuinfo files: procinfo/cpuinfo files

Python files (.py) are left allowed, since there is at least one syntax
check specifically for them.
