sysutils/fusefs-nbt: Update to 20230720-4d49ab2

- This change also fixes an issue where the built utilities may not always
  be using shared library libnbt.so.1 due to parallel building.

  Originally this port has 'ALL_TARGET=libnbt.so all', so make(1) will be
  launched with these 2 targets together; if parallel building is enabled
  (by default in ports tree), it is not guaranteed to have 'libnbt.so' ready
  before building 'all'. As a result some programs built by 'all' may have
  linked with libnbt.a instead. Fixing this unpredictable behavior by using
  2 make(1) passes for those 2 targets.
- Define USE_LDCONFIG
- Strip binaries
