scripts: dbgflags.py: Added support for flag aliases

Browse Source 
Also tweaked related flag comments a bit.

---

This adds another internal flag modifier ('a') to dbgflags.py to
indicate a flag is an alias for multiple other flags.

These still show up in -l/--list and name searches:

  $ ./scripts/dbgflags.py -l +ck
  LFS3_CK_MKCONSISTENT  0x00000100  Make the filesystem consistent
  LFS3_CK_LOOKAHEAD     0x00000200  Repopulate lookahead buffer
  LFS3_CK_COMPACT       0x00000800  Compact metadata logs
  LFS3_CK_CKMETA        0x00001000  Check metadata checksums
  LFS3_CK_CKDATA        0x00002000  Check metadata + data checksums
  LFS3_CK_CK            0x00003000  Alias for all check work
  LFS3_CK_GC            0x00003b00  Alias for all gc work

But are hidden from value searches, as they would be redundant and the
specific low-level flags are probably more useful:

  $ ./scripts/dbgflags.py +ck 0x00003000
  LFS3_CK_CKMETA  0x00001000  Check metadata checksums
  LFS3_CK_CKDATA  0x00002000  Check metadata + data checksums
