Remove some default error formats (solves bug with revtex4)

Using revtex4, the version line in the log file is matched by the default error formats of vim. This leads to confusing error messages.
The attached patch solve this (and comparable problems) by removing the responsible error formats.
The vim-latex code adds comparable, but less error-prone error formats, so that the default error formats are not necessary.

Description: Remove some default error formats.
The default error patterns, that are removed by this patch, match wrongly version
messages (for example of revtex4).
The comparable error formats in compiler/tex.vim are less error-prone.
