Fix BMC IP address detection on CoreOS images3.2.2
On CoreOS images, IPA runs in a Debian Jessie chroot which uses mawk as
its default awk implementation. However, mawk doesn't support POSIX
character classes such as [:space:], which means get_bmc_address() fails
to parse the BMC IP address from the output of ipmitool.
This patch replaces the use of [[:space:]] by [ \t] which is equivalent
for the purpose of parsing the output of ipmitool. Note that matching on
tab characters is not strictly required as the packaged version of
ipmitool only uses space characters, but is left in case tabs are used
in other versions.
