LibreELEC 10 Compatibility

[skinlayers]

Convert bash scripts to be POSIX compatible.
LibreELEC is based on busybox, so bash is actually an alias for ash on that platform.
ash doesn't support bare double-parenthesis for arithmetic evaluations, so they've been replaced with '[' (aka 'test') evaluations.

LibreELEC also use some different paths for SD card storage and additional python libraries. The sed commands below perform the appropriate edits, but these changes could be implemented directly with some conditional statements.

LibreELEC 10.0 instructions:
