Trdl client hanged when timeout has occured

[distorhead]

First attempt to add trdl repo failed with timeout error:

$ curl -sSL https://werf.io/install.sh | bash -s -- --ci
[INPUT REQUIRED] Current login shell is "bash". Press ENTER to setup werf for this shell or choose another one.
[b]ash/[z]sh/[a]bort? Default: bash.

— this process has failed with the error, but there also was a spawned background process, which hanged:

gitlab-+  137033  0.0  0.0   7232  1264 ?        S    03:46   0:00 bash -l

— this process held a file lock.

Next tries to run install script with trdl will always fail with file-lock timeout:

$ curl -sSL https://werf.io/install.sh | bash -s -- --ci

It is required to manually kill hanged background process to make trdl work again.
