[PATCHv2 2/3] cvsimport: fix the parsing of uppercase config options

The current code leads to

fatal: bad config value for 'cvsimport.r' in .git/config

for a standard use case with cvsimport.r set:

cvsimport sets internal variables by checking the config for each
possible command line option. The problem is that config items are case
insensitive, so config.r and config.R are the same. The ugly error is
due to that fact that cvsimport expects a bool for -R (and thus
config.R) but a remote name for -r (and thus config.r).

Fix this by making cvsimport expect the config item "cvsimport.RR"
for the command line option "-R" etc.
