parse/ConfHandler: Fix enthusiatic export regexp matching

The export regexp was only meant to catch values like:

export VARIABLENAME

however after the stricter quoting patch was applied, it was also matching
variables like:

export BAR=foo

and setting the export flag on a variable called "BAR=foo". The = character
is an invalid variable name character. This patch tightens up the regexp
match so it only matches the intended character set and only matches variable
names.
