[libvirt] [PATCH] docs: Format bit shift notation for bitwise flag enums

[Peter Krempa]

Big number itself does not make much sense in some cases. Format the
bitshift format as well.

Changes our web page docs from:

VIR_MIGRATE_POSTCOPY = 32768 : Setting the VIR_MIGRATE_POSTCOPY...
VIR_MIGRATE_TLS      = 65536 : Setting the VIR_MIGRATE_TLS flag...

to:

VIR_MIGRATE_POSTCOPY = 32768 (1<<15) : Setting the VIR_MIGRATE_POSTCOPY...
VIR_MIGRATE_TLS      = 65536 (1<<16) : Setting the VIR_MIGRATE_TLS flag...
