ICU-20545 Ensure that path ends with detected file separator

CharString, when asked, appends U_FILE_SEP_CHAR at the end of the string
it holds, if it won't find U_FILE_SEP_CHAR or U_FILE_ALT_SEP_CHAR there.
The problem starts if the dir variable uses
U_FILE_ALT_SEP_CHAR which is not equal to U_FILE_SEP_CHAR. Then the
resulting path could look like this
../data\
instead of this
../data/

This patch uses U_FILE_SEP_CHAR unless it detects that the dir variable
doesn't use it, and uses U_FILE_ALT_SEP_CHAR instead.
