    tdf#130080 soffice.sh: Avoid exporting empty LC_ALL
    
    The previous way of doing
    
        LO_SAVE_LC_ALL="$LC_ALL"
        LC_ALL=C
        export LC_ALL
        # ... (call some tools,...)
        LC_ALL="$LO_SAVE_LC_ALL"
    
    resulted in the LC_ALL environment variable explicity being
    set to an empty string in case it was not set at all previously.
    
    For some reason, an LC_ALL explicitly set to an empty string
    (other than an unset LC_ALL) makes the system ICU on various
    Linux distributions assume an "US-ASCII" encoding, even if the
    locale is otherwise configured to be a UTF-8 one.
    Since the corresponding detection from ICU is used in the
    KF5/Qt stack, that resulted in the Plasma-native file picker
    assuming an ASCII-encoding, and thus having problems with
    files containing non-ASCII characters.
    
    To avoid this, don't export LC_ALL if unset or set to an
    empty string.
    
    A big thanks to frinring on IRC #kde-devel for the analysis
    of why the Plasma-native file picker is affected by LC_ALL being
    set to an empty string!
    
    I could also reproduce that the following sample program run
    with 'LC_ALL=' on KDE Neon Developer edition printed "US-ASCII"
    when using the system ICU, while it printed "UTF-8" when using
    a self-built ICU as of current master (commit
    d6b88d49e3be7096baf3828776c2b482a8ed1780) instead, but did not
    further investigate why:
    
        #include <unicode/ucnv.h>
        #include <iostream>
    
        int main() {
            std::cout << ucnv_getDefaultName();
        }
