fix desktop file for linux

did NOT work because:
* .desktop files do not interpret shell-style escaping like $
* $SHELL expands incorrectly or becomes empty
* /bin/sh -c ends up with no valid command

• Working Exec lines:
  Exec=/bin/bash -ic "scrcpy --pause-on-exit=if-error"
  Exec=/bin/bash -ic "scrcpy"
  because:
  • bash -i loads .bashrc properly
  • .desktop can parse this line correctly
  • No confusing escaping is needed

The current version works for me. What's your config?

If you run explicitly with bash, then environment variables (like ADB) set for the default shell (for example zsh) will not work.

# For some users, the PATH or ADB environment variables are set from the shell
# startup file, like .bashrc or .zshrc… Run an interactive shell to get
# environment correctly initialized.

for me $SHELL is not expanding "Invalid environment variable name evaluates to an empty string: SHELL -i -c 'scrcpy --pause-on-exit=if-error'
/bin/sh: -c: option requires an argument"
