Fix build script in OS X

[nicolunacba]

In some platforms (like OS X) the sed command needs the parameter -i as -i.bak. Also, seems like OS X is strict about the order of the parameters in cp command.

Hello. -I.bak option seems to create unneeded backups of the changed files, which creates duplicate files in the output xpi.

@Exalm You're right. In order to not create backup files, I changed the sed command specifying a zero-length extension.

@Exalm Just installed a Linux VM and my change doesn't work on it. The only thing I can do is:

• keep -i.bak
• remove .bak files before create the zip by find . -type f -name "*.bak" -exec rm -f {} \;
