minitests: partial_reconfig_flow: Remove init/final sequence hacks 

Now that xc7series generates proper .bit files, the hacks need to be
removed.

# xc7patch currently only generates the actual frame writes which is
# insufficient to program a device. Grab the initialization and finalization
# sequences from the harness bitstream so they can be tacked on to the
# xc7patch-generated bitstream to create a programmable bitstream.
#
# The offsets used below were determined by manually inspecting
# harness.bit with a hex editor. init_sequence.bit is the beginning of
# the file until just before the actual frame data is sent via a write to FDRI.
# final_sequence.bin is from just after the frame data write to the end of the
# file. Note that final_sequence.bin normally includes at least one CRC check.
# The sed command replaces any CRC checks with a Reset CRC command which is the
# same behavior as setting BITSTREAM.GENERAL.CRC to Disabled. These offset
# should not change unless you alter the bitstream format used (i.e. setting
# BITSTREAM.GENERAL.DEBUGBITSTREAM or BITSTREAM.GENERAL.PERFRAMECRC to YES).
