android: Allow to override config file path from env

The HAL config file is assumed to be in the LIBCAMERA_SYSCONF_DIR
directory, which is defined by the meson build system at compile time.

As the filesystem layout on Android installations might be device/build
specific, allow to override such assumption using the
LIBCAMERA_HAL_CONFIG_PATH environment variable and document its usage.

While at it, remove quotes from the error message, as the file path
doesn't contain any space.
