config: fix specifying configuration value with equality sign
Currently there is a problem with parse_config_section() when the
configuration value contains equality sign like this for example:
MOUNT_OPTIONS="-o data=journal"
the result will be
export MOUNT_OPTIONS="-o data="journal"
which is not going to work. The reason is that the expression used to
parse the configuration options uses greedy matching '.*'. Fix this by
using non greedy expression to match the first equality sign '[^=]'.
