[PATCH] reset-db test: use the common definition of env/conn

Test builds fail with GCC 10 due to conflicting variable names:

/usr/bin/ld: exe/common.o:(.bss+0x8): multiple definition of `env'; /tmp/ccqfSqFX.o:(.bss+0x8): first defined here
/usr/bin/ld: exe/common.o:(.bss+0x0): multiple definition of `conn'; /tmp/ccqfSqFX.o:(.bss+0x0): first defined here
