[syslog-ng] [PATCH] confgen: backticks weren't processed in generated configuration part

[Juhász Viktor]

confgen: backticks weren't processed in generated configuration part

produced by confgen module. The reason of this problem was,
that the cfg_lexer_subst_args was called only for read lines
from configuration files (YY_INPUT) and for the processed blocks.

If process the backticks for a cfg input buffer is a must,
the cfg_lexer_subst_args has to be called explicit.
Now the confgen module call the it before set the include buffer to the lexer
