Fix for Bug #43973 - backup_myisam.test fails on 6.0-bugteam
The test started failing following the push for BUG#41541.
Some of the algorithms access bytes beyond the input data
and this can affect up to one byte less than "word size"
which is BITS_SAVED / 8.
Fixed by adding (BITS_SAVED / 8) -1 bytes to buffer size
(i.e. Memory Segment #2) to avoid accessing un-allocated data.
myisam/mi_packrec.c:
Fixed _mi_read_pack_info() method to allocate (BITS_SAVED/8) - 1
bytes to the Memory Segment #2
