mm-modem-helpers: add low_nybble_first argument to mm_bcd_to_string

Browse Source 
All BCD-encoded strings used by MM currently have the low nybble
of each byte come before the high nybble, but some strings (such
as the EID string returned by QMI Get Slot Status) are meant to
be read in order with the high nybble before the low one. As such,
extend mm_bcd_to_string to decode both.
