Installing on Replit

Hello,

I was make install -ing on a Replit container which lacks sudo capability ( ref: https://ask.replit.com/t/sudo-not-working/32834 ) and such borked the install on line ten of the Dexter Makefile under bash: ( ref: https://github.com/coinbase/dexter/blob/a56da61a2267a3cf5a16b778b78b0b27ac631681/Makefile#LL10C1-L11C1 )

I was hoping to open this issue and do a pull request to address this issue.

Thank you for your time and looking forward to hearing from you.
