default-providers: Set the preferred provider for bluez

There is a need for a default provider for bluez
now that bluez5 recipe is also present.

After the introduction of bluez5 recipe,
the following warnings are displayed:

"NOTE: multiple providers are available for runtime libasound-module-bluez (bluez4, bluez5)
 NOTE: consider defining a PREFERRED_PROVIDER entry to match libasound-module-bluez"

Upon debug, bitbake shows:
DEBUG: checking PREFERRED_PROVIDER_bluez4 (value None) against ['bluez4', 'bluez5']
DEBUG: checking PREFERRED_PROVIDER_bluez4-4.101 (value None) against ['bluez4', 'bluez5']
DEBUG: checking PREFERRED_PROVIDER_bluez4-4.101-r5 (value None) against ['bluez4', 'bluez5']
DEBUG: checking PREFERRED_PROVIDER_bluez5 (value None) against ['bluez4', 'bluez5']
DEBUG: checking PREFERRED_PROVIDER_bluez5-5.7 (value None) against ['bluez4', 'bluez5']
DEBUG: checking PREFERRED_PROVIDER_bluez5-5.7-r0 (value None) against ['bluez4', 'bluez5']

Bitbake is faced with the question "what should provide libasound-module-bluez?"
which is a runtime name. It needs to try and find a PREFERRED_PROVIDER entry
which matches this but those use *build time* naming. So it converts "libasound-module-bluez"
into the canonical ${PN} of bluez4 and bluez5 and then tries to look those up.
What it actually should do is go one step further of mapping bluez4/bluez5
into the virtual/bluez but that does not happen.

eglibc.inc: Remove quotation marks from OPTION_EGLIBC_NSSWITCH_FIXED_*

Kconfig outputs strings with quotation marks. When eglibc tries to see if
the paths exists, uses wildcard make function which doesn't strip out the
quotation marks - checking for path fails. So strip out the quotation
marks from OPTION_EGLIBC_NSSWITCH_FIXED_* option-groups.config.
(see nss/Makefile)

eglibc-options.inc: Fix string options

Add quotation marks for OPTION_EGLIBC_NSSWITCH_FIXED* options. If not, Kconfig
will ignore the value and will use the default one which is "".
