[Termux] Remove warnings on startup

[ilivetruth]

I am using ble.sh on my Android phone using termux, and everything works just fine.

How can I disable these warnings?

Also, thanks for building this awesome tool, I use it everywhere!

ble.sh: insane environment: $USER is empty. ble.sh: modified USER=u0 a516
ble.sh: The locale 'en_US.UTF-8' (LC_CTYPE) seems broken. Please check that the locale exists in the system.

This means that the variable USER is not set in your environment, which is the problem of the environment. For this error, you can set the user name in ~/.bashrc (before sourcing ble.sh):

# bashrc

: "${USER:=$(id -un)}"
export USER

ble.sh: The locale 'en_US.UTF-8' (LC_CTYPE) seems broken. Please check that the locale exists in the system.

This is an issue of the Termux environment, where the behavior of en_US.UTF-8 provided by the Termux environment is broken. This is already reported at #507. The situaion is described in https://github.com/termux/termux-packages/discussions/23010#discussioncomment-12487582 in detail. If you want to avoid this problem and do not use UTF-8, please set LANG=C (before sourcing ble.sh):

# bashrc

LANG=C

edit: This doesn't solve the underlying issue with the Termux locales, but it should at least suppress the error (by skipping the check).

In commit ea1e547bc0ffd39e62a2011b4b4530024d6c91da, I updated the warning message for the Termux environment to make it more precise. I also added a link to the upstream discussion.
