[PATCH] xfstests: fix specifying configuration value with equality sign

[Lukas Czerner <lczerner@xxxxxxxxxx>]

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 '[^=]'.
