MDEV-15496: wsrep_sst_common - parse IPv6 correct

Browse Source 
Fix to e78e308e81, IPv6 got split at :

Also got rid of awk (yuck!) to parse port (commit: b4fbb4183b)

Tested with dash to avoid bashisms:

$ dash -vx './wsrep_sst_common.sh' --address '128.0.0.5:3333/module/lsn_version/sst_ver/some_future_option1/some_future_option2' 2>&1  | more
+ readonly WSREP_SST_OPT_ADDR=128.0.0.5:3333/module/lsn_version/sst_ver/some_future_option1/some_future_option2
+ readonly WSREP_SST_OPT_HOST=128.0.0.5
+ readonly WSREP_SST_OPT_HOST_UNESCAPED=128.0.0.5
+ remain=3333/module/lsn_version/sst_ver/some_future_option1/some_future_option2
+ readonly WSREP_SST_OPT_PORT=3333
+ remain=module/lsn_version/sst_ver/some_future_option1/some_future_option2

+ readonly WSREP_SST_OPT_LSN=lsn_version
+ remain=sst_ver/some_future_option1/some_future_option2
+ readonly WSREP_SST_OPT_SST_VER=sst_ver

$ dash -vx './wsrep_sst_common.sh' --address '[2001:db8::1]:3333/module/lsn_version/sst_ver/some_future_option1/some_future_option2' 2>&1  | more

And bash as well:
