Fixed issue with case-sensitivty of server spec name in
configurable values. For example, if the server spec name
is p4d_edge_SITEX and is case-insensitive, the configurables
displayed with p4d -cshow can look like P4D_EDGE_sitex and
still be valid.
An example of an issue this fixes that an edge server being
migrated from Windows to Linux could have the run_if_edge.sh
script fail to determine that the server is an edge server;
a daily_checkpoint.sh would run fine interactively but would
fail to execute from the crontab, due to the run_if_edge.sh
not detecting it was an edge. The situation that could cause
this would be that a ServerID could be p4d_edge_SYD but the
lbr.replication configurable could be set as
P4D_EDGE_SYD#lbr.replication=readonly
